CHEM 1C Study Guide - Final Guide: Blood Plasma, Sodium Hydroxide, Lead
Document Summary
Determine the ph of a 0. 20m nh3 solution. Then determine the ph of a solution that is 0. 20m nh3 and also 0. 30m nh4cl. Another example: calculate the ph of the solution that results from mixing 0. 200l of 0. 050m (ch3)2nh with 0. 320l of 0. 040m (ch3)2nh2cl. You try: calculate the ph of the solution that results from mixing 72. 0ml of 0. 015m (ch3)2nh with. The ph of blood plasma is 7. 40, assuming the principal buffer system is hco3. Calculate the ph of 1. 00l of the buffer 1. 00m ch3coona and 1. 00m ch3cooh: before and after the addition of b) 0. 080 mol naoh or c) 0. 120 mol hcl. :h2co3 is 20:1, we also said the the ph of blood is around 7. 4. Explain, give an explanation if it doesn"t for why it can still be true. (ka= 4. 5x10-7 and. A 10. 0 ml solution of 0. 300m nh3 is titrated with a 0. 200m hcl solution. Calculate the ph after the following additions of the hcl solution.
