Question

For the dihydrogen arsenate ion, H_2AsO^- _4: what is its conjugate acid? ____ what is its conjugate base? ___ Explain how one can measure the heat of vaporization of a volatile liquid. Be quite specific, both about what data you would collect and how you would actually calculate the heat of vaporization from the data. For the reaction, AgCl(s) leftwardsarrowoverrightwardsarrow Ag^+ (aq) + Cl^- (aq) delta H = +65.5 kJ/mole. What will happen to the [Ag^+] if; a. NaCl was added to the equilibrium mixture? Explain.

Explanation / Answer

Ans 15.

For a simple understanding of a conjugate acid and base , one should always remember that , an acid molecule always gives its proton to form a conjugate base .

So the conjugate acid will have a proton more than its base . The conjugate acid of H2AsO4-

will be H3AsO4.

Likewise the conjugate base will have a proton less , so the conjugate base of H2AsO4- will be HAsO42-
