Question

iv. The concentration of H30+ ions decrease on diluting the acid.
v. Curd and sour substances should not be kept in brass and copper vessels.​

Answer 1

Answer:

The concentration of hydronium ions decreases when an acid is diluted because on adding water the H+ ions of the acid and hydroxyl ions of water react to form water molecules and the concentration of hydronium ions decreases. When an acid is diluted, then the concentration of hydronium ions decreases.

Explanation:

Answer 2

Answer:

1. The concentration of hydronium ions decreases when an acid is diluted because on adding water the H+ ions of the acid and hydroxyl ions of water react to form water molecules and the concentration of hydronium ions decreases. When an acid is diluted, then the concentration of hydronium ions decreases.
2. The concentration of hydronium ions decreases when an acid is diluted because on adding water the H+ ions of the acid and hydroxyl ions of water react to form water molecules and the concentration of hydronium ions decreases. When an acid is diluted, then the concentration of hydronium ions decreases.If these kinds of substances which possess acids are kept in copper containers or vessels they will react and produce salt and hydrogen and the vessel will be corroded. It can also produce harmful products that may spoil the food.
