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.

1. Aluminum sulfate can be made by the following reaction: 2AlCl3(aq)+3 H2SO4(aq)➡Al(SO4)3(aq)+6HCl(aq). It is quit soluble in water, so to isolate it the solution has to be evaporated to dryness. This drives off the volatile HCl, but the residual solid has to be heated to a little over 200 celsius to drive off the water. In one experiment, 25.0 g of AlCl3 were mixed with 30.0 g of H2SO4. Eventually, 28.46 g of pure Al2(SO4)3 were isolated. Calculate the percentage yield. 2.
