Chem Exam 3 Things to Know 100% Verified Review Solution 2024/2025 Before starting a titration equation, what do we need to find? - ANS-Ka/Kb (given the other), volume, concentration of acid and base, initial mols of weak acid/base at the starting point of a titration, how do you find pH? - ANS-use a RICE table to find K expression equation, plug initial (not titrant) concentration into table and when you have K expression, solve for X. take -log of x for pH at the buffer region of a ti...

TBR Chemistry Ch. 5 Exam Questions & Answers 2024 Buffer - ANSWER-a solution where pH remains relatively constant after the addition of either strong acid or strong base. Can be made by combining a conjugate pair in roughly equal mole portions (must be weak acid/base pair). The addition of strong base or strong acid shifts teh ratio of weak acid (HA) to its conjugate base (A⁻), but the pH does not change, if the A⁻:HA ratio is close to 1.0 Can also be made by partially titrating a...

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 ...
