Calculate the concentration of calcium 2 plus in a solution if anything is left after mixing calcium 2 plus and carbonate solutions.
00:10
So here let's start with the reaction of the dissolution of calcium carbonate and after mixing of e2 equals volumes, the concentration of calcium 2 plus and total concentration of co3 will drop twice because we mix 100 and 100 milliliters.
00:29
Now, let's assume that x of calcium carbonate dissolves and therefore the concentration of calcium 2 plus in the solution is x.
00:40
Concentration of carbonate is different.
00:42
It's x, which is formed from calcium carbonate plus this difference between total concentration of co3 and concentration of calcium 2 plus.
00:52
So basically, this is the amount of carbonate which is left over after the reaction.
00:57
So therefore we can derive the equation shown here, which shows the constant, the solubility constants of calcium carbonate.
01:13
And from this equation, we can find x, which is a root of quadratic equation shown here...
