Question

is AgCl insoluable?

Answer 1

Salts containing Cl-, Br-, I- are generally soluble. Important exceptions to this rule are halide salts of Ag+, Pb2+, and (Hg2)2+. Thus, AgCl, PbBr2, and Hg2Cl2 are all insoluble.
Cl- All chlorides are soluble except AgCl, Hg2Cl2, and PbCl2.

Answer 4

Do you know a trick to figuring these out? I am having trouble using the chart.

Answer 5

After you give me the answer I can see how you got it, but before that just trying to use the chart I am lost.

Answer 6

Just gotta know the rules. Some teachers give out absurdly complicated tables. If I were you, I'd go and use this one:

But really it's just all memorization of the rules.
Also, knowing your periodic table is helpful. Knowing things like Ag=silver is pretty crucial.
