Calculating concentrations in solution. Interactive exercises. I.

Abstract

An exercise to assess and improve your knowledge on calculations of concentrations in solution. It consists of three parts. In the first one, you have to find the concentration of Cu(II) in a sample analyzed by the iodometric method. Then, we will analyse the content of chloride in a bottled water by ISE (ion selective electrode ). The calculated value has to be written on the bottle label. Finally, a standard solution of copper and nickel will be prepared by accurate weighing of soluble salts of these cations. The concentration of these species in the solution must be calculated.
