A buffer solution that is 0.403 M in HF and 0.403 M in NaF has a pH of 3.14.

(1) The addition of 0.01 mol of H₃O⁺ to 1.0 L of this buffer would cause the pH to _________increase slightly increase by 2 units decrease slightly decrease by 2 units not change.

(2) The capacity of this buffer for added H₃O⁺could be increased by the addition of 0.148 mol_________of the weak acid of the salt.

Consider these compounds:

A. CaCrO₄

B. Fe₂S₃

C. CaCO₃

D. Ca₃(PO₄)₂

Complete the following statements by entering the letter corresponding to the correct compound.

Without doing any calculations it is possible to determine that zinc phosphate is more soluble than , and zinc phosphate is less soluble than .

It is not possible to determine whether zinc phosphate is more or less soluble than by simply comparing K_sp values.

Please show your work and be specific, I have asked these questions already and got the wrong answers because they weren't answered fully!
