Expressing concentration of solutions

Firstly, we will understand about the term solutions. Afterwards, we will discuss the ways of expressing concentration of solutions. Expressing the concentration of the solutions A solution is a homogeneous mixture of two or more chemically non reacting solute and solvent components. Solute is the component which is present in lesser amount in the solution. […]
