Some Quizzes About Sulfurous Acid

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.

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.

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).

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.

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.

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.

The molar mass of the given substance is 82 g/mol.

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.
