A Single 1 L Aqueous Stock Solution Is Made By Adding The Following Amounts Of Three Readily Soluble Salts 7 20g


A single 1 L aqueous stock solution is made by adding the following amounts of three readily soluble salts: 7.20g

NaCl, 0.17g CaCl2 and 0.37g KCl. Remember that all of these salts fully dissociate in water. (This solution is commonly known as Ringer’s Solution and is used in medicine to hydrate patients).

a). Express the concentration of each cation in the solution as mmol/L.

b). What is the total concentration of chloride ion expressed in mmol/L.

The solution to this problem requires a number of similar calculations for each ion. They are easier to solve if you organize your calculations using a consistent format.
