how do you find solubility of

Pb(NO3)2, PbCl2, PbCrO4, and PbS

Do you have a textbook?

To find the solubility of a substance, you need to consult a solubility table or use the solubility rules for common ions. Here's how you can determine the solubility of each compound you mentioned:

1. Pb(NO3)2 (Lead(II) Nitrate): Nitrate (NO3-) salts are generally soluble, so Pb(NO3)2 is also soluble in water.
2. PbCl2 (Lead(II) Chloride): Chloride (Cl-) salts are usually soluble, except for a few exceptions such as AgCl, Hg2Cl2, and PbCl2. Therefore, PbCl2 is generally insoluble in water.
3. PbCrO4 (Lead(II) Chromate): Chromate (CrO4--) salts are generally insoluble, except for a few exceptions such as the alkali metal chromates. Therefore, PbCrO4 is generally insoluble in water.
4. PbS (Lead(II) Sulfide): Sulfide (S2-) salts are usually insoluble, except for a few exceptions such as the alkali metal sulfides. Therefore, PbS is generally insoluble in water.

It is important to note that these are general solubility rules, and there might be specific conditions under which these salts could exhibit variable solubility. Always refer to reliable sources or consult a solubility table to get accurate and up-to-date information on solubility.

not on me sadly it is at school.
