A) Sodium dihydrogen phosphate
B) Disodium hydrogen phosphate
C) Sodium phosphate
D) Phosphoric acid
Correct Answer: B
Solution :
The basicity of an acid is the number of hydrogen ions \[(H+)\] which can be produced by the ionization of one molecule of the acid in aqueous solution. For example, the basicity of hydrochloric acid is 1 since one molecule of \[HCl\]produces one \[H+\] ion in solution. Similarly, the basicity of Disodium phosphate \[(N{{a}_{2}}HP{{O}_{4}})\] is one since it has one \[H+\] displaceable ion.You need to login to perform this action.
