Certainly, the calcium hydroxide solution will be more concentrated under the conditions.

Explanation:

#"Concentration"# is a measure of the number of particles in solution. You have equal strength concentrations of calcium hydroxide and sodium hydroxides with respect to the metal. Calcium hydroxide, however, delivers twice the hydroxide ion concentration as does sodium hydroxide. The calcium hydroxide solution contains more ions in solution.
