Question

Chose the statements that are TRUE from the list below Group of answer choices Ions exist alone in nature Lactate is created by our muscles during anaerobic glycolysis, it reacts with water to form lactic acid. We add calcium carbonate to lakes after acid rain because the calcium ion is basic and will react with the acid. If Lake A has a limestone base and Lake B has a granite base, after each receive the same acid rain fall, Lake B will be more acidic than Lake A Fluorine anion is a weak base because hydrofluoric acid is a weak acid All salts are either acidic or basic after being dissolved in water.

Answer 1

Answer:

Explanation:

1 ) Lactate is created by our muscles during anaerobic glycolysis, it reacts with water to form lactic acid  - True

2 ) We add calcium carbonate to lakes after acid rain because the calcium ion is basic and will react with the acid. True

3 )  If Lake A has a limestone base and Lake B has a granite base, after each receive the same acid rain fall, Lake B will be more acidic than Lake A : True

limestone is calcium carbonate which is basic but granite is not basic so it can not neutralise acid. So lake B remains more acidic .

4 ) Fluorine anion is a weak base because hydrofluoric acid is a weak acid False

A weak acid has strong anion . Hydrofluoric acid is weak but fluorine anion is strong.

5 ) All salts are either acidic or basic after being dissolved in water false .

Neutral salts are also found.
