Regents Chemistry Exam June 2024 Question 37
37 Based on Table F, which compound is most soluble in water?
(1) calcium bromide (3) silver carbonate
(2) lead(II) sulfate (4) tin(II) hydroxide
Solution:
Table F on the Reference Table gives solubility guidelines. Let's go one by one for the answer choices. Calcium bromide consists of calcium and bromine. Bromide ion is found in the left column and is said to be soluble unless combined with Ag+, Pb2+, or Hg2+, which calcium is not. Calcium bromide is soluble. Choice 1 is the correct answer choice. All the other choices will be insoluble according to table F.
