Question

Define the term acid and acidic​

Answer 1

Explanation:

ACID : Acid, any substance that in water solution tastes sour, changes the colour of certain indicators (e.g., reddens blue litmus paper), reacts with some metals (e.g., iron) to liberate hydrogen, reacts with bases to form salts, and promotes certain chemical reactions (acid catalysis).

ACIDIC : An acidic solution has a high concentration of hydrogen ions (H +start superscript, plus, end superscript), greater than that of pure water. A basic solution has a low H +start superscript, plus, end superscript concentration, less than that of pure water.
