Introduction

Solubility is a fundamental concept in chemistry that refers to the ability of a substance to dissolve in a solvent, typically water. It is a crucial property that determines the behavior of compounds in various chemical reactions and processes. In this article, we will determine the solubility of the given compounds and identify which ones are soluble.

Solubility Rules

Before we proceed with the analysis, it is essential to understand the solubility rules that govern the behavior of compounds. These rules are based on the chemical properties of the ions involved and are used to predict the solubility of compounds.

Sodium, potassium, and ammonium compounds: These compounds are generally soluble in water, except for those containing carbonate, phosphate, and silicate ions.
Nitrate and acetate compounds: These compounds are generally soluble in water.
Chloride, bromide, and iodide compounds: These compounds are generally soluble in water, except for those containing silver, lead, and mercury ions.
Sulfate compounds: These compounds are generally soluble in water, except for those containing barium, strontium, and lead ions.
Carbonate and phosphate compounds: These compounds are generally insoluble in water, except for those containing sodium, potassium, and ammonium ions.

Analysis of Compounds

$CoCO_3$

$CoCO_3$ is a carbonate compound containing cobalt and carbonate ions. According to the solubility rules, carbonate compounds are generally insoluble in water, except for those containing sodium, potassium, and ammonium ions. Since cobalt is not one of these ions, $CoCO_3$ is expected to be insoluble in water.

$CuI_2$

$CuI_2$ is an iodide compound containing copper and iodide ions. According to the solubility rules, chloride, bromide, and iodide compounds are generally soluble in water, except for those containing silver, lead, and mercury ions. Since copper is not one of these ions, $CuI_2$ is expected to be soluble in water.

$Na_2CO_3$

$Na_2CO_3$ is a carbonate compound containing sodium and carbonate ions. According to the solubility rules, carbonate compounds are generally insoluble in water, except for those containing sodium, potassium, and ammonium ions. Since sodium is one of these ions, $Na_2CO_3$ is expected to be soluble in water.

AgCl

AgCl is a chloride compound containing silver and chloride ions. According to the solubility rules, chloride, bromide, and iodide compounds are generally soluble in water, except for those containing silver, lead, and mercury ions. Since silver is one of these ions, AgCl is expected to be insoluble in water.

$Pb(NO_3)_2$

$Pb(NO_3)_2$ is a nitrate compound containing lead and nitrate ions. According to the solubility rules, nitrate and acetate compounds are generally soluble in water. Since lead is not one of the exceptions, $Pb(NO_3)_2$ is expected to be soluble in water.

LiOH

LiOH is a hydroxide compound containing lithium and hydroxide ions. According to the solubility rules, hydroxide compounds are generally soluble in water, except for those containing silver, lead, and mercury ions. Since lithium is not one of these ions, LiOH is expected to be soluble in water.

$K_3PO_4$

$K_3PO_4$ is a phosphate compound containing potassium and phosphate ions. According to the solubility rules, phosphate compounds are generally insoluble in water, except for those containing sodium, potassium, and ammonium ions. Since potassium is one of these ions, $K_3PO_4$ is expected to be soluble in water.

Conclusion

In conclusion, the following compounds are soluble in water:

$CuI_2$
$Na_2CO_3$
$Pb(NO_3)_2$
LiOH
$K_3PO_4$

The following compounds are insoluble in water:

$CoCO_3$
AgCl

It is essential to note that the solubility of compounds can be affected by various factors, including temperature and pressure. Therefore, the solubility of these compounds may vary under different conditions.
