PROPERTIES OF WATER

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Vinegar is an example of:
A
Strong Acid
B
Weak Acid
C
Strong Base
D
Weak Base
Explanation: 

Detailed explanation-1: -Vinegar is a weak acid because it is not very good at transferring H+ ions to water. In a 1 M solution, less than 0.4% of the CH3CO2H molecules react with water to form H3O+ and CH3CO2-ions. More than 99.6% of the acetic acid molecules remain intact.

Detailed explanation-2: -Through a two-part fermentation process, yeast and bacteria are used to turn the sugar into ethanol (ethyl alcohol), which is then processed into acetic acid. It is the acetic acid content in vinegar that makes it acidic.

Detailed explanation-3: -Strong acids consist of seven main acids – chloric acid, hydrobromic acid, hydrochloric acid, hydroiodic acid, nitric acid, perchloric acid, and sulfuric acid. These can completely dissociate in water, giving them the title of strong acid.

Detailed explanation-4: -Vinegar is a combination of acetic acid and water made by a two-step fermentation process.
