Write conjugate acids of (i) CO_(3)^(2-) (ii) H_(2)O (iii) OH^(-) (iv) HSO_(4)^(-) .
What is the basicity of H_3PO_4 ?
How H_(3)PO_(3) is diprotic acid?
The oxidation state of P in (H_3PO_2) is
What is the basicity of H_3PO_3 ?
Under the influemce of an electric field, the particles in a sol migrate towards cathode. The coagulation of the same sol is studied using NaCl,Na_(2)SO_(4) , and Na_(3)PO_(4) solutions. Their coagulation values will in the order a. NaClgtNa_(2)SO_(4)gtNa_(3)PO_(4) b. Na_(2)SO_(4)gtNa_(3)PO_(4)gtNaCl c. Na_(3)PO_(4)gtNa_(2)SO_(4)gtNaCl d. Na_(2)SO_(4)gtNaClgtNa_(3)PO_(4)
The K_(a) values for HPO_(4)^(2-) and HSO_(3)^(-) are 4.8xx10^(-13) and 6.3xx10^(8) repectively. Therefore, it follows the HPO_(4)^(2-) is … acid than HSO_(3)^(-) and PO_(4)^(3-) is a …… base than SO_(3)^(2-)
