Distilled white vinegar is used for cooking but can also be used in many applications for cleaning. The active ingredient in vinegar is acetic acid (CH3COOH,pka = 4.74). If a brand of household vinegar produces a pH of 4.2, what is the initial molar concentration of acetic acid (assuming it is the only substance contributing to pH)? o A 2 .19x104M O B 8.7x10-'M O C 4.10x10 M O D 1.0x10-'M Unanswered Submit

Triprotic acid (Homework), IV Homework Unanswered hat is the pH of a 0.20 M solution of disodium hydrogen phosphate? Ka 2-62 x 10-3 and Ka,-2.2 x 10-13 ?
A chemist needs to determine the concentration of a solution of nitric acid, HNO3. She puts 875 mLof the acid in a flask along with a few drops of indicator. She then slowly adds 0.200 MBa(OH)2 to the flask until the solution turns pink, indicating the equivalence point of the titration. She notes that 145 mL of Ba(OH)2 was needed to reach the equivalence point. Solution map In this titration, the concentration of base is known and can be used...
