Calcium phosphate and cahpo4)

The theory is that calcium phosphate soluble in water, cahpo4 slightly soluble in water, its water solution is the basic

The experiment supplies and reagents: beaker glass tube litmus test paper reagent phenolphthalein PH

The experiment steps: 1. The calcium phosphate and were taken DCP small, join in the beaker, plus a small amount of water, dissolves.

2. In two beaker, adding phenolphthalein,

The experiment phenomenon: a beaker of liquid to become red, is DCP, another beaker discoloration, is calcium phosphate.

Conclusion: calcium phosphate soluble in water, cahpo4 slightly soluble in water, its water solution is the basic
