Question

Are all substances mixed in water to determine [H+] or acidity/basic nature or pH of the substance? If yes, what are the conditions e.g. how much water is required? Also how does H2O ionize when the substance is dissolved?

Answer 1

Answer:

mark me brainlinest

Explanation:

Adding water to an acid or base will change its pH. Water is mostly water molecules so adding water to an acid or base reduces the concentration of ions in the solution. When an acidic solution is diluted with water the concentration of H + ions decreases and the pH of the solution increases towards 7.
