If pH of a solution decreases from 5 to 2, then it is

The pH of an aqueous solution decreases form 3 to 2. What will happen to the nature of the solution ?

A : pH of 1 M NaCI solution is 7 at 25^@C . R : pH of this solution decreases when it is diluted 100 times

A : pH of 1 M NaCI solution is 7 at 25^@C . R : pH of this solution decreases when it is diluted 100 times

If the pH values of solutions X, Y and Z are 13, 6 and 2 respectively then does the pH value of a solution increase or decrease when a base is added to it '? Why?

The pH of a solution is 5. to this solution acid was added so that its pH value bcomes 2.0. The increase in H^(+) concentration is :

The pH of 0.1 M solution of a weak acid (HA) is 4.50. It is neutralised with certain ammount of NaOH solution to decrease the acid content to half of initial value. Calculate the pH of the resulting solution.

The pH of 0.001 M solution of a weak acid (HA) is 4.50. It is neutralised with certain ammount of NaOH solution to decrease the acid content to half of initial value. Calculate the pH of the resulting solution.
