Question

50 mL solution of 0.2 M H₂SO₄ is titrated until neutralized with 25 mL NaOH. Calculate the molarity of NaOH solution.

Answer 1

Ans 50 ml solutions of 0.2 m Hasoy is titrated until neutralized with 25 ml Naon. So moles of H250 = 0.2 moles 50xl63 letre litre * -0.01 moles H2SO4 +2 Naow - Naz SD4 + 2 H2O so for I moles of H2SO4 = 2 maes of Nash requires Then Naor required 2x o.ol = 0.02 moles of Moly

volume of NaoH = 25 ml Then molarity of Nash 20020 modes & 25 ml 0.020 moles 25x10 3 litre Mnaor - 0.8 moles litre
