Question

Ques.If 40ml of NaOH solution is titrated with 20ml of H2SO4 solution having molarity 0.5M Find Molarity of Base (NaOH) and also calculate number of Na+ ions present in final solution ​

Answer 1

First determine the moles of NaOH in the reaction. From the mole ratio, calculate the moles of H2SO4 that reacted. Finally, divide the moles of H2SO4 by its volume to get the molarity
