Abstract

Solvent is the liquid part of a solution in which solute is dissolved. The solid chemical or substance that is dissolved in a solution is called solute. The types of solutions are prepared in the biochemistry laboratory following as normal solution, saturated solution, percent (%) solution, molar solution (m), molal solution, standard solution, formality (f), and mole fraction (x). Normal solution is a solution that contains the gram equivalent weight of a reagent per liter of solution. Saturated solution is a solution in which the maximum amount of solvent has been dissolved. A molar solution is a solution that contains 1 mole of solute in each liter of solution. A mole is the molecular weight (MW) expressed as grams.
