Document Summary

Will have assigned seating (check your email later) Review questions: which of the following would provide a weak acid but still be a strong electrolyte, ch 3 cooh, nh 4 no 3, ncl, h 2 so 4, none of the answer choices are correct. A weak acid is by default a weak electrolyte. Ch 3 cooh is a weak acid (by the table of acid) By referencing the solubility chart, kcl is a strong electrolyte, but it"s not an acid. Nh 4 no 3 is a strong electrolyte (by referencing the solubility chart), and when dissolved in. , which by referencing the acid chart is a weak acid. water it dissociates into nh 4 . Answer: nh 4 no 3: 600 ml of a 0. 35 m solution of k 2 s is mixed with 400 ml of an 0. 40 m zncl 2 . Nothing here is given in excess, therefore it is a limiting reagent question.
