Ion Concentration

Determination of Calcium Ion Concentration

the concentration in mol L−1 of Ca2+ in your sample solution. 4. Calculate the concentration, in mg/L (parts per million or ppm), of Ca2+ in your sample solution. 5. In the case of a solid sample which has been dissolved in acid, the concentration of Ca2+ in your sample solution may be used to calculate the percentage, by weight, of CaCO 3

Each ion is attracted to the surrounding water molecules and pulled off and away from the crystal When it enters the solution, the ion is surrounded by water molecules, insulating it from other ions The result is a solution with free moving charged particles able to conduct electricity 18 Tro: Chemistry: A Molecular Approach, 2/e
