characteristics of acid and base
Answers
Answer:
Acids and bases are compounds with one important thing in common: When you immerse them in solution, they release free ions. In an aqueous solution, which is the most common, the traditional way to differentiate them is that an acid releases positive hydrogen (H+) ions while a base releases negative hydroxide (OH-) ones. Chemists measure the strength of an acid or base by its pH, which is a term that refers to the "power of hydrogen." The midpoint of the pH scale is neutral. Compounds with a pH lower than the midpoint value are acidic while those with a higher value are basic or alkaline.
