The molar mass of potassium hydrogen phthalate (KHC8H4O4, abbreviation KHP) is 204.22 grams per mole. To determine the molarity of an unknown NaOH solution, a student weighed out 1.32 g of solid KHP and dissolved the solid in 25.4 mL of DI water. The resulting solution was used in a titration with the unknown NaOH solution (3 drops of phenolphthalein was used as an indicator). The balance chemical equation is given below. If the student used 15.06 mL of the unknown NaOH solution in the titration, what is the molarity of the NaOH solution

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.
