Exam 3 Genchem 2

What’s the first step of any titration

find equivalence point using MV=MV

How to find initial pH of strong b/a titration

use molarity of the strong acid and plug into -log(M)

finding pH before equivalence in strong b/a titration

make a BAA table using the initial moles of what’s given to you and subtract the moles of what’s added to it(it’s used). Then divide moles by total volume(volume of what you used for initial and volume of added), then plug in to find pH

finding pH at equivalence for strong b/a titration

it will equal 7

finding pH after equivalence for strong b/a titration

same as before equivalence, but if what is left is OH, you’ll need to subtract pOH from 14

finding initial pH of weak acid/strong base titration

use ice table on acid and plug x into -log

finding pH before equivalence on weak acid strong base titration

use a BAA table and then plug the moles into hendersson hasslebach equation

finding pH at equivalence on weak acid strong base titration

when doing BAA table, there should be conjugate left. create an ice table to see what this conjugate does in water(basically reverse the formula). since its conjugate should be a base, use Kb, find x, and then find pH from this pOH

finding pH after equivalence on weak acid strong base titration

find molarity of the moles of OH^- from BAA table and use it to get pOH
