1. A weak acid, HA, has a pKa of 4.11. a) At pH 7.11, what will the ratio of conjugate base to acid be? (Henderson-Hasselbach equation: pH=pKa + log [A-]/[HA]) b) Based on answer to "a," is there more HA or A- at that pH? c) At pH 2.11, what will the ratio of conjugate base to acid be? d) Based on answer to "c," is there more HA or A- at that pH? e) At pH 4.11, what will the ratio of conjugate base to acid be? f) Fill in the blank: if pH is greater than the pKa of a weak acid, there w...

CEM 142 MOCK EXAM 2 QUESTIONS AND ANSWERS ALREADY PASSED Imagine a reaction in which compound A (which is a blue compound) reacts with compound B (which is a yellow compound) to give AB. A2 + B2 --> 2AB What can you say about the color of compound AB? It is impossible to predict what the color of AB is from the information given Which acid is the strongest of CH4 NH3 OH2 and HF HF because H and F are small atoms - more bond overlap, not willing to share electrons, most positive ...
