5) On an episode of CSI Miami, a murder is committed by pushing a guy into a pool that is "alkali." The murder added what appeared to be 80 lbs (36.287kg) of pure sodium hydroxide (40 g/mol) into a pool (2,500,000 L). The good guys run to the store and come back with five gallons (18.257 L) of vinegar (%5 acetic acid, -0.75 M), and "neutralize" the pool. What is the pH of the pool before neutralization? What is the pH after "neutralization." Ka for acetic acid 1.78 x 10s pH before: pH after:

5) On an episode of CSI Miami, a murder is committed by pushing a guy into a pool that is
"alkali." The murder added what appeared to be 80 lbs (36.287kg) of pure sodium hydroxide (40
g/mol) into a pool (2,500,000 L). The good guys run to the store and come back with five gallons
(18.257 L) of vinegar (%5 acetic acid, -0.75 M), and "neutralize" the pool. What is the pH of the
pool before neutralization? What is the pH after "neutralization." Ka for acetic acid 1.78 x 10s
pH before
pH after:
bonus (+2) how many gallon containers would they need to make the pool safe to swim if it were
pH 13?
