How do you determine if a compound is soluble or insoluble E

Solution

Solubility of a solute can be determined by comparing the polarities of the solute and the solvent molecules. Polar solvents will dissolve polar solutes and nonpolar solvents will dissolve non-polar solutes due to the presence of similar intermolecular forces.

all three molecule are soluble molecule

all Compounds are soluble if they contain alkali metals, including Li⁺, Na⁺, K

Although calcium chloride is highly soluble in water at ordinary temperatures,

all nitrates are soluble so calcium nitrate is soluble phosphates of alkali ions (Li+,Na+,K+,Rb+,Cs+,Fr+) and NH4+ are soluble
