You will need two series of standard solutions to calibrate your ion-selective electrodes - one series for sodium and one for calcium. For the calcium ion create a procedure for preparing a 0.100 M solution from the solid, Anyhydrous Calcium Chloride, CaCl2. Make sure to include amounts and equipment you will use for the preparation.

Based off of the question above,create a procedure for preparing a series of additional standard solutions from the 0.100 M solution.
