Answer 1

Is the ionic compound CaCO3 soluble or insoluble, and does each of its ions tend to be soluble?

1. Both ions soluble b. Both ions insoluble c. Ions differ; soluble d. Ions differ; insoluble

Eg CaCl2 is soluble where as CaCO3 is insoluble there ions are different

1. Both ions soluble b. Both ions insoluble c. Ions differ; soluble d. Ions differ; insoluble

Most of the salts with NO3-/Na+ are soluble

Is the ionic compound AgBr soluble or insoluble, and does each of its ions tend to be soluble?

1. Both ions soluble b. Both ions insoluble c. Ions differ; soluble d. Ions differ; insoluble

Some salts of Ag+ is soluble Eg. Ag(NO3); where as AgBr is not

Is the ionic compound (NH4)3PO4 soluble or insoluble, and does each of its ions tend to be soluble?

1. Both ions soluble b. Both ions insoluble c. Ions differ; soluble d. Ions differ; insoluble

Ca(PO4)2 is insoluble but (NH4)3PO4 is soluble

I have given you examples of soluble/insoluble salts of same ions so that you get an idea why the choice of answer.
