A stock solution of nitric acid is found in the back of the chem stock room, but the concentration on the label is illegible. Andy decides to determine its concentration with a titration, so it can be relabeled. She prepares a stock solution of NaOH by adding 150.g to 2.50 L of water. What is the concentration of the NaOH stock solution? She adds an indicator to a 200. mL sample of the nitric acid solution and find that it takes 670. mL of the NaOH solution to reach the equivalence point. How many moles of NaOH were added? What is the concentration of the stock solution of nitric acid?

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.
