A few drop of conc HCL are added to about 10cm${}^3$ of a solution of PH 3.4. The PH of the resulting mixture is

Answer Details

The pH of the resulting mixture will be less than 3.4. pH is a measure of the acidity or basicity of a solution and ranges from 0 to 14. A pH of 7 is neutral, a pH less than 7 is acidic, and a pH greater than 7 is basic. When a few drops of concentrated hydrochloric acid (HCl) are added to a solution with a pH of 3.4, the HCl will lower the pH of the solution. This is because HCl is a strong acid and will donate hydrogen ions (H+) to the solution, increasing the concentration of H+ ions and thus making the solution more acidic. The exact pH of the resulting mixture will depend on the amount of HCl added and the original concentration of the pH 3.4 solution.
