Three solutions made with water

A solution is made when one substance called the solute "dissolves" into another substance called the solvent. ... This break up is caused by coming into contact with the solvent. In the case of salt water, the water molecules break off salt molecules from the larger crystal lattice.

Explanation: A solution is a homogenous (uniform throughout) mixture, on a molecular level, of two or more substances. For example, in a solution of salt and water, water is the solvent and salt is the solute. ... Solutions are formed because the molecules of the solute are attracted to the molecules of the solvent.

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
