Answer 1

Explanation:

Acid staining is a finishing technique for concrete that mixes water, hydrochloric acid, and acid-soluble metallic salts. This mixture penetrates and chemically reacts with the hydrated lime in the concrete. The stain lightly etches the concrete surface, which allows the metallic salts to penetrate easier.

Answer 2

$\huge\purple{\mathbb{Answer♡}}$

All acids may be organic or inorganic, releasing hydrogen ions (H+) in water. Hence, acid is defined as “a substance which gives out hydrogen ions when dissolved in water”.
