Any substance that in water solution tastes sour, changes the colour of acid-base indicators (e.g., litmus), reacts with some metals (e.g., iron) to yield hydrogen gas, reacts with bases to form salts, and promotes certain chemical reactions (e.g.,...

A liquid that reacts with metallic oxides to form SALTS and water; reacts with (most) metals to produce salt and hydrogen; or reacts with carbonates to produce salts, CARBON DIOXIDE and water. Although they are not ELECTROLYTES in pure form, they...
