Question
Calcium phosphate is present in tooth enamel. Its nature is(a) basic(b) acidic(c) neutral(d) amphoteric
Solution
The nature of calcium phosphate is (a) basic.
Here's why:
Calcium phosphate is a salt of calcium and phosphate. In water, it partially ionizes to form Ca2+ ions and PO4^3- ions. The PO4^3- ion can accept a proton (H+) from water to form HPO4^2- and OH- ions. The formation of OH- ions increases the pH of the solution, making it basic. Therefore, calcium phosphate is considered basic in nature.
