ACID And Base Naming

The name for the given base KOH is Potassium Hydroxide.

The given chemical formula, Ca(OH)2, represents a compound called calcium hydroxide. In this compound, calcium (Ca) is bonded to two hydroxide (OH) groups. Calcium hydroxide is commonly used in various applications such as in the production of cement, as a flocculant in water treatment, and as an ingredient in certain dental materials.

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.

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.

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.

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.

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.

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.

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 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.

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.

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.

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.

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.

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.
