which of the following salt is (are) soluble in aqueus solution? 1. lead nitrate 2. lead sulfide 3. lead carbo

Question

a) 1 and 2 only b) 2 only c) 1 only d) 3 only e) 1,2 and 3

Answer 1

C. Only lead nitrate is soluble. Lead carbonate and lead sulfide are for all intents and purposes insoluble (you'll see how much when you study solubility products).

Answer 2

I know that all nitrates are soluble. I cannot remember the exceptions about sulfides, and I don't know what the last one is since the letters were cut off the question.

Consult your text and find the table of solubilities. You will find your answer there.
