Question

Consider a 2 M solution of Magnesium Chloride. What is the concentration of total ions (+ and -) in the solution?

Answer 1

`MgCl_2 rightleftharpoons Mg^(2+) + 2Cl^(-)`

Explanation:

If the solution is `2*mol*L^-1` with respect to `"magnesium chloride"`, the concentration of `"ions"` is `6*mol*L^-1`, i.e. `3` equiv ions per equiv of salt.
