a. Na2CO3
b. PbSO4
c. AgBr
d. K2S
I know how to find out if it is soluble if I am given the solubility of of the liquid in water at a cetain temp., but I do not know how to do it if I am not given that information. Thanks for the help.

PbSO4 is insoluble.
"Sulfates are soluble with the exception that compounds of Lead, Silver, Mercury, Barium, Strontium, and Calcium are insoluble."
AgBr is also insoluble.
"Bromides are soluble with the exception that compounds of Silver, Mercury, and Lead are insoluble"

Is Agbr Soluble In Water

Lead Sulphate and Silver Bromide are insoluble. The main reason being they cannot form hydrogen bond with water due to their non affinity towards water.

Check your chemistry book for a table of Solubility Products, or the Solubility Product constant (Ksp). The value for Ksp for a substance is the product of the concentration of the cation and the concentration of the anion, each raised to the power of the subscript of that ion:
For an insoluble compound (M)a(X)b, the equation would be:
Ksp = [M+] ^a * [X-]^b
Insoluble substances, such as lead sulfate or silver bromide, will have VERY small values of Ksp. For example,
PbSO4: Ksp = 2.53 x 10^-8 = [Pb+2] * [SO4-2]
AgBr: Ksp = 5.35 x 10^-13 = [Ag] * [Br-]
You can remove more Pb from a saturated solution of lead sulfate by adding sulfuric acid, since that would increase the concentration of [SO4-2]. Likewise, you could remove more silver by adding a soluble bromide salt, such as ammonium bromide or sodium bromide.

b and c are insoluble. Some general rules - sodium and potassium salts are soluble in water. Many sulfates, phosphates and carbonates are insoluble in water.

alkali metals and alkali earth metals are usually soluble. That leaves D,E,and B. I thought all nitrates were soluble. The other guy is wrong. Its gotta be D or E. I place by bets on E.

You have to find the Ksp on your book.
AgBr is a slightly soluble salt .
Ksp = 5.0 x 10^-13
Na2CO3 is a strong salt >> 2 Na+ + CO32-
PbSO4 is a slightly soluble salt
Ksp = 1.6 x 10^-8
K2S is a strong salt >> 2 K+ + S2-
