Question

how is pH of a solution of an acid influenced when it is diluted

Answer 1

when acid is diluted ,its pH will increase as pH of acid is less than 7.
The pH of water is 7. I hope this will help u.

Answer 2

Explanation:

Relation between pH and hydrogen ion concentration is as follows.

                             pH = $-log [H^{+}]$

And, when we dilute an acid then there will occur a decrease in the concentration of $H^{+}$ ions. As a result, there will occur an increase in pH of the solution.

Since, it is known that when pH of a solution is less than 7 then it is acidic in nature. pH equal to 7 then the solution is neutral in nature. When pH is greater than 7 then the solution is basic in nature.

Thus, we can conclude that pH of a solution of an acid increases when it is diluted.
