Questions and Answers
  • 1. 

    What is the formula of sulfurous acid?

    • A.

      H2SO3

    • B.

      HSO3

    • C.

      H2SO4

    • D.

      HSO4

    Correct Answer
    A. H2SO3
    Explanation
    The correct formula for sulfurous acid is H2SO3. This is because sulfurous acid is a weak acid that is formed when sulfur dioxide dissolves in water. The formula indicates that there are two hydrogen atoms (H2) and one sulfur atom (S) bonded to three oxygen atoms (O3).

    Its molar mass is _________ g/mol

    • A.

      80

    • B.

      81

    • C.

      82

    • D.

      83

    Correct Answer
    C. 82
    Explanation
    The molar mass of the given substance is 82 g/mol.

  • 3. 

    Sulfurous acid is most commonly a __________. 

    • A.

      Solid

    • B.

      Liquid

    • C.

      Gas

    Correct Answer
    B. Liquid
    Explanation
    Sulfurous acid is most commonly a liquid because it is formed when sulfur dioxide (SO2) dissolves in water. The resulting solution is a weak acid that exists in a liquid state.

  • 4. 

    It is most often used in _____________

    • A.

      Disinfectants

    • B.

      Toothpaste

    • C.

      Air freshener

    Correct Answer
    A. Disinfectants
    Explanation
    Disinfectants are the most common and frequent application for the given answer. Disinfectants are substances used to kill or inhibit the growth of microorganisms on surfaces, objects, or living tissues. They are commonly used in hospitals, households, and other settings to prevent the spread of diseases and maintain cleanliness. While toothpaste and air fresheners may have some antibacterial properties, their primary purpose is not disinfection.

  • 5. 

    Is sulfurous acid weak, strong or neutral?

    • A.

      Weak

    • B.

      Strong

    • C.

      Neutral

    Correct Answer
    A. Weak
    Explanation
    Sulfurous acid is weak because it only partially dissociates in water, resulting in a small number of hydrogen ions being released. This is due to its low ionization constant, indicating that it does not completely break apart into ions. In contrast, strong acids fully dissociate in water, releasing a large number of hydrogen ions. Neutral substances do not have acidic or basic properties.

    It is most commonly this color.

    • A.

      Colorless

    • B.

      White

    • C.

      Green

    • D.

      Red

    Correct Answer
    A. Colorless
    Explanation
    The given statement suggests that the color being referred to is the most common one. Since colorless is the absence of color, it can be considered the most common color as it does not have any specific hue. Therefore, colorless is the correct answer.

    Sulfurous acid is a _________________

    • A.

      Rusting agent

    • B.

      Reducing agent

    • C.

      Decomposing agent

    • D.

      Oxidizing agent

    Correct Answer
    B. Reducing agent
    Explanation
    Sulfurous acid is a reducing agent because it has the ability to donate electrons to other substances, causing them to gain electrons and be reduced. In the case of rusting, sulfurous acid can react with oxygen in the air, preventing the oxidation of iron and thus inhibiting the formation of rust.

    It is very common in ___________

    • A.

      Salts

    • B.

      Gases

    • C.

      Volcanoes

    Correct Answer
    A. Salts
    Explanation
    Salts are very common in various natural environments such as oceans, lakes, and underground deposits. They are formed when acids react with bases, resulting in the formation of ionic compounds. Salts are also commonly found in our daily lives, such as table salt (sodium chloride) used for cooking and preserving food. Therefore, it is reasonable to say that salts are very common in nature.
