Copper (II) sulfate is a fungicide widely used in agriculture and gardening. In one of the university laboratories, a copper sulfate bottle was found without identifying the hydration water (CuSO4.XH2O). To find this value, a mass equal to 1.1000 g of CUSO4.×H20 was oven dried for 1 h at 110°C. Calculate the value of x, knowing that the water content was equal to 36.40% (w/w).

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.
