ion concentration of the solution.

b) It represents the number of H atoms present in the solution.

c) It represents the oxidizing strength of solution

d) It represents the tending of reduction​

Answer 1

Answer:

à) pH is a measure of how acidic/basic water is. The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.

b)Since the pH is the negative logarithm of the hydrogen ion concentration, low pH numbers, e.g. pH 6.2, indicate relatively high hydrogen ion concentrations, i.e. an acidic solution. High pH numbers, e.g. pH 7.8, represent lower hydrogen ion concentrations, i.e. alkaline solutions.
