In a chemical reaction, equilibrium is said to  have been established when the

Calculate the pH of a solution formed by mixing equal volume of solution having pH value 2 and 4.

Calculate the pH of a buffer solution containing equimolar amount of `HX` and `X^-` if the `K_a` for `HX` is `10^-8`

If `K_(sp)` of `Mg(OH)_2=1**10^-(11)` , the pH above which `Mg(OH)_2` starts to precipitate from a solution containing `…

In order to increase the pH of solution by 3 times, the solution should be diluted by

If hydrogen ion concentration of an acid is decreased by 100 times, the pH will increases by:

A characteristic feature of reversible reaction is that

The chemical reaction which proceed in forward direction only is called an
