42.5 mL of 1.3M KOH are required to neutralize 50.0 mL of H2SO4. This sulfuric acid is further used to standardize NaOH solution. 20mL aliquot of the NaOH solution is obtained and 2 drops of phenolphthalein is added. The initial reading on the buret is 13.2 mL. After the titration, the exact normality of the NaOH solution is found to be 1.254N. (a) What is the molarity of H2SO4? (b) How much of the sulfuric acid is used? (c) What is the final reading on the buret?

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
