Please help me......

a. Do you expect the pH at the equivalence to be lowest when a 0.0500 M (CH₃)₃N(aq) solution or a C5H5N(aq) solution is titrated with a 0.0500 M HCl(aq) solution at 25.0

^oC? Motivate your answer! (CH₃)₃N (K_b = 6.5 × 10^-5) and C5H5N (K_b = 1.7×10^-9) are

weak monoprotic bases.

Calculate the pH at the equivalence point and 25 ^oC when 1.00 L of a 0.0500 M

C5H5N(aq) solution is titrated with a 0.0500 M HCl(aq) solution.
Calculate the molar solubility for CaCO₃ in a 0.060 M Ca(NO₃)₂(aq) solution. K_sp=

3.1 × 10^-9 for CaCO₃.
