    What is the range of the ph of an acid

    • 2-4

    • 3-10

    • 0-6

    Correct Answer
    A. 0-6
    Explanation
    The range of the pH of an acid is 0-6. This is because pH is a scale that measures the acidity or alkalinity of a substance, with 0 being the most acidic and 14 being the most alkaline. Since acids have a pH below 7, the range of 0-6 indicates that an acid can have a pH anywhere within that range.

    Rate this question:

  • 4. 

    The pH scale ranges from

    • 1 to 7

    • 1 to 20

    • 1 to 14

    • 1 to 10

    • 1 to 100

    Correct Answer
    A. 1 to 14
    Explanation
    The pH scale measures the acidity or alkalinity of a substance. It ranges from 1 to 14, with 1 being the most acidic and 14 being the most alkaline. A pH value of 7 is considered neutral, indicating neither acidity nor alkalinity. This scale is logarithmic, meaning that each whole number change represents a tenfold difference in acidity or alkalinity. Therefore, a substance with a pH of 2 is ten times more acidic than a substance with a pH of 3.

    What is the name of H2S

    • Sulfous Acid

    • Hydrosulfuric Acid

    • Sulfuric Acid

    • Hydrogen Sulfur Acid

    Correct Answer
    A. Hydrosulfuric Acid
    Explanation
    Hydrosulfuric acid is the correct answer because it is the common name for H2S, which is a chemical compound consisting of hydrogen and sulfur. Sulfous acid, sulfuric acid, and hydrogen sulfur acid are incorrect names for H2S. Sulfous acid does not accurately represent the composition of H2S, sulfuric acid contains additional oxygen atoms, and hydrogen sulfur acid is not a recognized name for the compound. Therefore, the correct name for H2S is hydrosulfuric acid.

    What is the name of H3P

    • Phospourous Acid

    • Hydrophosphoric Acid

    • Phosphic Acid

    • Hydrogen Phosphorous Acid

    Correct Answer
    A. Hydrophosphoric Acid
    Explanation
    Hydrophosphoric acid is the correct answer because H3P is the chemical formula for hydrophosphoric acid. The other options are not correct as they do not match the given chemical formula. Phosphorous acid has the formula H3PO3, phosphic acid has the formula H3PO4, and hydrogen phosphorous acid does not exist as a known compound. Therefore, hydrophosphoric acid is the only option that matches the given chemical formula H3P.

    What's the correct formula of HydroFlouric Acid?

    • HF3

    • HF

    • H2F

    Correct Answer
    A. HF
    Explanation
    HydroFlouric Acid is represented by the chemical formula HF. The symbol H represents hydrogen, and the symbol F represents fluorine. Therefore, HF is the correct formula for HydroFlouric Acid.

    What's the correct formula of Sulfuric  Acid?

    • H2SO4K3

    • H2SO4

    • H2S

    Correct Answer
    A. H2SO4
    Explanation
    Sulfuric acid is represented by the chemical formula H2SO4. This molecular formula indicates that each molecule of sulfuric acid consists of two hydrogen atoms, one sulfur atom, and four oxygen atoms. It is a highly corrosive and strong acid widely used in various industrial processes.

    What are the properties of a neutral substance?

    • PH Range 1-3

    • PH Range 4-6

    • PH = 7

    • PH Range 8-10

    • PH Range 11-14

    • Bitter

    • Sour

    • Slippery

    • Sting

    • Conducts electricity well

    • Dim light bulb

    • Reacts with metal

    • Reacts with CO3

    • Turns litmus blue

    • Turns litmus red

    Correct Answer
    A. pH = 7
    Explanation
    A neutral substance has a pH value of 7, which means it is neither acidic nor basic. It is considered to be in a balanced state. This is because in a neutral substance, the concentration of hydrogen ions (H+) is equal to the concentration of hydroxide ions (OH-). Therefore, it does not exhibit any of the properties associated with acidity or alkalinity, such as sour taste, bitter taste, slipperiness, stinging sensation, or color changes in litmus paper. Additionally, a neutral substance does not react with metals or CO3, and it does not conduct electricity well or affect the brightness of a light bulb.

    What's the name of  H3PO4

    • Phosphous Acid

    • Phosphoric acid

    • Hydrophosphoric Acid

    • Hydrogen Phouspourous Acid

    Correct Answer
    A. Phosphoric acid
    Explanation
    Phosphoric Acid is the correct answer because H3PO4 is the chemical formula for this compound. Phosphoric Acid is a mineral acid that contains phosphorus in its +5 oxidation state. It is commonly used in various industries, such as fertilizers, detergents, and food additives.

    Arrhenius Bases always have what in them?

    • H

    • OH

    • Polyatomics

    • None of the choices are correct.

    Correct Answer
    A. OH
    Explanation
    Arrhenius bases always have OH in them. This is because Arrhenius bases are substances that dissociate in water to produce hydroxide ions (OH-) as the only negative ions. Therefore, the presence of OH- ions is a characteristic feature of Arrhenius bases.

    Arrhenius Acids always have what in them?

    • H

    • OH

    • Polyatomics

    • None of the choices are correct.

    Correct Answer
    A. H
    Explanation
    Arrhenius Acids always have hydrogen (H) in them. This is because Arrhenius Acids are substances that, when dissolved in water, release hydrogen ions (H+). These hydrogen ions are responsible for the acidic properties of the solution. Therefore, the presence of hydrogen is a characteristic feature of Arrhenius Acids.

    Which of the followiong are ternary acids?

    • HClO3

    • H2SO3

    • H2S

    • HCl

    Correct Answer(s)
    A. HClO3
    A. H2SO3
    Explanation
    The correct answer is HClO3 and H2SO3. Ternary acids are acids that contain three different elements: hydrogen, oxygen, and another element. HClO3 (chloric acid) and H2SO3 (sulfurous acid) both fit this definition as they contain hydrogen, oxygen, and chlorine or sulfur respectively. H2S (hydrogen sulfide) and HCl (hydrochloric acid) do not contain oxygen and therefore do not qualify as ternary acids.

    What's the name of  H3PO3           Po3 = phosphite

    • Phosphorus Acid

    • Phosphic Acid

    • Hydrophosphoric Acid

    • Hydrogen Phouspourous Acid

    Correct Answer
    A. Phosphorus Acid
    Explanation
    The chemical compound H3PO3 is named phosphorous acid. This is because the anion (PO3)^3- is referred to as phosphite, and when it forms an acid with hydrogen, the resulting compound is phosphorous acid, not to be confused with phosphoric acid, which is H3PO4.

    Which of the followiong are binary acids?

    • HClO3

    • H2SO3

    • H2S

    • HCl

    Correct Answer(s)
    A. H2S
    A. HCl
    Explanation
    The compounds H2S and HCl are binary acids because they consist of only two elements, hydrogen and a nonmetal (sulfur and chlorine, respectively). Binary acids are a type of acid in which hydrogen is bonded to a nonmetal, and they typically have the prefix "hydro-" followed by the nonmetal name and the suffix "-ic" (e.g., hydrochloric acid). HClO3 and H2SO3 are not binary acids because they contain additional elements (oxygen) in addition to hydrogen and a nonmetal.

    A. pH Range 1-3
    A. Sour
    A. Sting
    A. Conducts electricity well
    A. Reacts with metal
    Explanation
    Strong acids have a pH range of 1-3, meaning they are highly acidic. They taste sour and can cause a stinging sensation. They also conduct electricity well, indicating the presence of ions in solution. Additionally, strong acids react with metals, producing hydrogen gas.

    Correct Answer(s)
    A. pH Range 11-14
    A. Bitter
    A. Slippery
    A. Conducts electricity well
    A. Reacts with CO3
    Explanation
    A strong base has a pH range of 11-14, indicating that it is highly alkaline. It is bitter in taste and has a slippery texture. Strong bases are also good conductors of electricity, as they dissociate into ions in water. They react with CO3, which refers to their ability to react with carbonate ions.
