Concept explainers
(a)
Interpretation:
The compound with higher molar solubility in the given pair of compound needs to be determined.
NH4Cl or NaCl at 40°C
Concept introduction:
Ionic compounds are soluble in polar solvents as “Like dissolves like.” Therefore, polar solvents like water act as a good solvent for ionic compounds.
The solubility curve can be used to determine the solubility in water at different temperature. Some of solutes / compounds are more soluble in water whereas some are quite less. The solubility curve indicates the relation in the solubility of different ionic compounds in water at different temperatures.
(b)
Interpretation:
The compound with higher molar solubility in the given pair of compound needs to be determined.
CuSO4 and or K2SO4 at 20°C
Concept introduction:
Ionic compounds are soluble in polar solvents as “Like dissolves like.” Therefore, polar solvents like water act as a good solvent for ionic compounds.

- Some lithium chloride, LiCl, is dissolved in 100 mL of water in one beaker, and some Li2SO4 is dissolved in 100 mL of water in another beaker. Both are at 10 C, and both are saturated solutions; some solid remains undissolved in each beaker. Describe what you would observe as the temperature is raised. The following data are available to you from a handbook of chemistry:arrow_forwardIndicate whether or not the two members of each of the following pairs of compounds have like solubility (both soluble or both insoluble). a.
