To a basic buffer solution 3 drops of 0.1 M HCl solution is added. Still its pH remains same. Account for the observation.

Number of HCl molecules present in 10 mL of 0.1 N HCl solution is

Fill in the biank P_H of .01 M KOH solution will be____

The sum of pH and pKb for a certain basic buffer solution is 13. The ratio of the concentration of the base to that of the salts in this buffer is

10 mL of 2(M) NaOH solution is added to 200 mL of 0.5 (M) of NaOH solution. What is the final concentration of the resultant solution?

A buffer solution contains 0.1 M of acetic acid and 0.1 M of sodium acetate. What will be its pH ? ( pK_(a) of acetic acid is 4.75)
