Question

i really have no idea about this part about the solubility generalization rules

Part B:Solubility Generalizations (up to 7 points) Copy the statements you wrote in your lab notebook here while performing the experiment. There are 7 anions and 10 cations for up to 17 statements, although you may combine some into one statement, see example on page 6. point for each correct, non-duplicated statement. You will earn 1.

Answer 1

Solubility generalizations

1. Ionic compounds containing carbonate ion (CO3^2-) are typically insoluble except when combined with Na+, K+, and NH4+.

2. Ionic compounds containing phosphate ion (PO4^3-) are typically insoluble except when combined with Na+, K+, and NH4+.

3. Ionic compounds containing oxalate ion (C2O4^2-), chromate ion (CrO4^2-) are typically insoluble except when combined with Na+, K+, and NH4+

4. Most sulfides (S^2-) of transition metals are highly insoluble.

5. Most hydroxide salts are slightly soluble. Hydroxide salts of group 1 and group 2 are slightly soluble. Hydroxide salts of transition metals and Al³⁺ are insoluble.

6. All salts of group 1 NH4+, K+ and Na+ are mostly soluble.

7. Salts containing anion nitrate (NO3^2-), chlorate (ClO3^-), perchlorate (ClO4^-), and acetate (CH3CO2^-) are soluble.

8. All salts containing anion Cl-, Br- and I- are soluble. Exceptional halides of Ag+, Pb+, and Hg+ are insoluble.

9. All silver salts are insoluble. Except AgNO3 and Ag(CH3CO2) are soluble.

10. Salts containing sulfate anion are soluble. Except sulfate salts containing cations Ca2+, Sr2+, Ba2+, Pb2+ and Ag+ are insoluble.

11. Salts containing fluoride anion are soluble. Except sulfate salts containing cations Ca2+, Sr2+, Ba2+, Pb2+ and Mg2+ are insoluble.
