A 6.0mL sample of 50.0% (m/v) acetic acid (HC2H3O2) solution is added to water to give a final volume of 25mL . Give the answer using 2 significant figures. According to my text, C2 = C1 *V1/V2, so wouldn't it be 25 = 50,0 * 19/25 = 38%? However, in the online exerci...

Acetic acid only in the protease group exceeded 1.0. Propionic acid in the CK and protease groups were detected and both reached the highest value at 3 d. After 30 days of fermentation, the lactic acid content of the P15 + ZZUPF95 group was higher than that in other groups, ...
Next, 0.05% acetic acid was added into the chitosan solution to produce a homogenous solution of chitosan. Approximately, 0.1 to 0.5 g of mechanically exfoliated graphene was added into the homogenous solution of chitosan using continuous stirring at 300 rpm for 2 h at room temperature (~ 30...
(pH-6.6), and 5 mL of 1% ferricyanide was added and incubated for 20 min at 500C. After incubation the 10% trichloro acetic acid (TCA) added and centrifuged at 3000 rpm for 10 min. Equal amounts of water and 1 mL of 1% ferric chloride were added to the supernatant, absorbance read...

Some things you have to memorize. Carbonic acid and acetic acid are weak. Ammonia is a weak base. Rule of thumb says that salts of weak acids and/or weak bases hydrolize changing pH of solution. Salts of strong acids and bases don't hydrolize. ...
