25 ml of a solution of barium hydroxide on titration with a 0.1 molar solution of hydrochloric acid gave a titre value of 35ml. The molarity of barium hydroxide solution was:

0.1 M HCl has pH = 1.0, it is about 100 times stronger than nitric acid. Then pH of acetic acid will be

1.0 M solution of NaOH is mixed with 1.0 M solution of H₂SO₄+ the solution formed is:

100 ml of each of 0.5 N NaOH, N/5 HCl and N/10 H2SO4 are mixed together. The resulting solution will be:

100 ml of N/5 NaOH will neutralize:

A buffer solution is that which resists/minimizes the change in:
