Calc. Ca2+ in Standard Carbonate Soln. w/ Na2CO3 Addition

[carmikeisevil]

In what general way could I go about finding out M of Ca 2+ given a standard calcium carbonate solution and after the addition of 3 X 10 ^ -4 M of sodium carbonate at 25 degrees Celsius.

I haven't done chemistry in years and would appreciate any help getting started.

You will need to know how to use the Ksp of calcium carbonate in this calculation.

Is M referring to molar mass (n) or molar concentration (c) or am I just misinterpreting the question?

 

[chemisttree]

'M' is Molarity.

When you say "25 degrees Celsius," are you referring to SATP?
