Question #ad761
1 Answer
Michael and Doreen are correct, calcium carbonate is considered insoluble in water, which is another way of saying that very, very little amounts will actually dissolve.
You can use calcium carbonate's solubility product constant,
The very small amount of calcium carbonate that does dissolve will dissociate into
By definition,
The
This is calcium carbonate's molar solubility in water at a temperature of
This means that you cannot add more than 0.0053 g of calcium carbonate to a liter of water without making a saturated solution.
So, at best, your 100-mL volume of water can only hold
The molarity of the
Far from the 0.5 M of your target solution.
That's the best you can hope for in that much volume of water.
