In this problem, we are asked to describe the solubility of calcium carbonate compared to water in first a solution of 0 .10 molar sodium chloride.
00:16
In each of the four situations that we're going to be given, we're supposed to answer whether the solubility was the same as water, less soluble than in water, or more soluble in water.
00:27
In sodium chloride, it will have the same solubility as in water.
00:34
The sodium and the chloride neither are common to the calcium or the carbonate.
00:57
So it's not going to have any effect.
01:03
B, our second substance is 0 .10 molar calcium nitrate.
01:17
And that will be less soluble.
01:19
And that is because the calcium ion is common.
01:34
So the ca2 plus shifts the equilibrium to the left.
01:52
And i should have written the equation...
