A sample of material contains the components NaOH, Na2CO3, NaHCO3 , or possible mixtures of these. Two samples, each weighing 1 .000 gram, are dissolved in water. To one sample phenolphthalein is added and the solution is titrated cold with 1.038 N acid, of which 17.96 ml are required. The other sample is titrated cold with methyl orange as an indicator, and 21.17 ml of the same acid is required. Calculate the percentage of alkalies present.

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.
