Explanation:
the pH of the solution defined as negatuve logarithm of ion concentration.
1. Hydrogen ion concentration when pH of the solution is 11.
..(1)
At pH = 11, the concentration of ions is
.
2. Hydrogen ion concentration when the pH of the solution is 6.
..(2)
At pH = 6, the concentration of ions is
.
3. On dividing (1) by (2).
The ratio of hydrogen ions in solution of pH equal to 11 to the solution of pH equal to 6 is .
4. Difference between the ions at both pH:
This means that Hydrogen ions in a solution at pH = 7 has ions fewer than in a solution at a pH = 6
