6 questions on acids and alkalis


Questions and Answers
  • 1. 

    Which of the following has the chemical formula H2SO

    • A.

      Carbonic acid

    • B.

      Carbon dioxide

    • C.

      Sulphur dioxide

    • D.

      Sulphuric acid

    • E.

      Sulphur carbonate

    Correct Answer
    D. Sulphuric acid
    Explanation
    Sulphuric acid has the chemical formula H2SO4. It is a strong acid that is commonly used in various industrial processes such as the production of fertilizers, dyes, and detergents. It is also used in laboratories and as a laboratory reagent. The chemical formula H2SO4 indicates that each molecule of sulphuric acid contains two hydrogen atoms, one sulphur atom, and four oxygen atoms.

    What type of chemical contains hydroxide ions?

    • A.

      Acid

    • B.

      Alkali

    • C.

      Carbonate

    • D.

      Oxide

    • E.

      Ammonium

    Correct Answer
    B. Alkali
    Explanation
    An alkali is a type of chemical that contains hydroxide ions. Hydroxide ions have a negative charge and consist of one oxygen atom bonded to one hydrogen atom. Alkalis are known for their ability to neutralize acids and have a pH value greater than 7. They are commonly found in household cleaning products and are often used in industries such as agriculture, manufacturing, and water treatment.

    What is the charge of hydrogen ions in acids?

    • A.

      Negative

    • B.

      Positive

    • C.

      Neutral

    • D.

      No charge

    • E.

      Alternating current

    Correct Answer
    B. Positive
    Explanation
    Hydrogen ions in acids have a positive charge. When an acid dissolves in water, it releases hydrogen ions (H+), which are positively charged. These hydrogen ions are responsible for the acidic properties of the solution, as they can donate a proton to other substances. Therefore, the correct answer is positive.

    What is a mole?

    • A.

      Gram formula mass

    • B.

      A compound with the same chemical formula, but a different structural formula

    • C.

      A family of hydrocarbons with a general formula and similar properties

    • D.

      Unit of concentration

    • E.

      Unit of measurement for liquids

    Correct Answer
    A. Gram formula mass
    Explanation
    A mole is a unit of measurement used in chemistry to express the amount of a substance. It is defined as the amount of a substance that contains the same number of particles (atoms, molecules, or ions) as there are in 12 grams of carbon-12. The gram formula mass refers to the mass of one mole of a compound, which is calculated by adding up the atomic masses of all the atoms in its chemical formula. Therefore, the gram formula mass is a correct explanation for what a mole is.

    Which is the acid?

    • A.

      Lye

    • B.

      Vinegar

    • C.

      Amylase

    • D.

      Fructose

    • E.

      Starch

    Correct Answer
    B. Vinegar
    Explanation
    Vinegar is the correct answer because it is an acidic substance. It is made through a fermentation process that converts ethanol into acetic acid. Vinegar has a sour taste and is commonly used in cooking and as a cleaning agent. Lye, amylase, fructose, and starch are not acids.

  • 6. 

    Name the only gas which dissolves to give an alkali solution?

    • A.

      Carbon dioxide

    • B.

      Sulphur dioxide

    • C.

      Ammonia

    • D.

      Nitrogen dioxide

    • E.

      Carbon monoxide

    Correct Answer
    C. Ammonia
    Explanation
    Ammonia is the only gas among the options that dissolves to give an alkali solution. When ammonia gas dissolves in water, it forms ammonium hydroxide, which is a strong base and gives an alkaline solution. Carbon dioxide, sulphur dioxide, nitrogen dioxide, and carbon monoxide do not dissolve to form alkali solutions.
