Introduction: Concentration of a solution can be defined as the amount of the solute in a fixed amount of a solvent or a solution. Concentration can be expressed in many different ways. A few of them are: percent composition, parts per million, parts per billion, molarity, molality, normality and formality. The most commonly used is the molarity, which is defined as the number of moles of solute present in one litre of the solution. Knowing the concentration of solutions is a very important aspect, specifically in the field of medicine. In case of a medicine is prescribed by a doctor, the concentration of the components present in the medicine play an important role. The intravenous injections given to us have the same concentration of the solute as the concentration of the solute present in the blood. It means the solution in case of the medicine should be isotonic with the blood. If it is not, then the movement of the substances will take pace either into the cells or out of the cells, which might make the cells swell or shrink. The purpose of this lab is to find the concentration of the unknown solution, located at the front. If more water is added to the substance, then the solution will become less concentrated with the copper sulphate substance. Also the colour will change, if the solution is more concentrated, then it will stay a darker shade of blue, but if it is less concentrated, it will get lighter than the more concentrated solution. To find the concentration of
