The basicity of H3PO4 is:
Correct answer: C. 3
- A. 1
- B. 2
- C. 3
- D. 4
Explanation
Basicity means the number of replaceable hydrogen atoms. H3PO4 = 3H+ + PO4- For hydrogen to be acidic, it must be attached to a strongly electronegative atom. Here it is attached to 3 oxygen. Hence the basicity of H3PO4 is 3.
