Stoichiometry Exploration Discussion.

Below is a picture of 4 test tubes. Each one contains the products of the reaction between 0.1 M CuCl₂ and 0.1 M Na₃PO₄, but each one had a different ratio of the solutions added.

copper phospate

Here is a table that shows what was added to each (A - D) from left to right.

Test Tube	Volume of CuCl₂ Added (mL)	Volume of Na₃PO₄ Added (mL)	Ratio CuCl2:Na₃PO₄
A	5	20	1:4
B	10	15	3:2
C	15	10	2:3
D	20	5	4:1

Topics for discussion:

What is the balanced reaction?
What is the blue product?
Why does test tube C have the most? Does it have anything to do with the reaction?
Why do test tubes A and B have colorless solutions above the blue precipitate, C is slightly blue and D is more so?
Why doesn't A have the least amount of precipitate?
