Question

Which one is the correct option for the solubility of $\text{CuC}{{\text{l}}_{\text{2}}}$ ​ in water?
A) sparingly soluble
B) completely soluble
C) insoluble
D) soluble at higher temperature

Answer 1

The ability of a solid, liquid, or gaseous chemical substance called a solute to dissolve in a solid, liquid, or gaseous solvent is known as solubility. The physical and chemical characteristics of the solute and solvent, as well as temperature, pressure, and the presence of additional chemicals (including variations in pH) in the solution, all influence the solubility of a material. The saturation concentration of a material in a given solvent is the point at which adding more solute does not raise the concentration of the solution and begins to precipitate the excess quantity of solute.

Complete Step By Step Answer:
When soluble salts dissolve in water, the ions in the solid separate and spread evenly throughout the solution, which is referred to as dissociation.
The kind of ions (cation and anion) that make up ionic compounds determines their solubility in water. A collection of empirical principles established based on observations of numerous ionic compounds can be used to predict the solubility of a salt.
I) Ammonium ions and alkali metal cations are soluble in compounds.
ii) Nitrates and acetates are insoluble in all cases.
iii) With the exception of silver, lead, and mercury, chloride, bromide, and iodide compounds are soluble (I)
iv) Except for their salts with silver, lead, mercury(I), barium, strontium, and calcium, all sulphate salts are soluble.
v) Except for their salts with ammonium and alkali metal cations, all carbonates, sulfites, and phosphates are insoluble.
. A soluble salt like potassium chloride ( $\text{CuC}{{\text{l}}_{\text{2}}}$ ) is an example. When solid $\text{CuC}{{\text{l}}_{\text{2}}}$ is introduced to water, the polar water molecules' positive (hydrogen) ends are attracted to the negative chloride ions, while the negative (oxygen) ends are drawn to the positive copper ions. Individual $C{{u}^{2+}}$ and $C{{l}^{-}}$ ions are surrounded by water molecules, which reduce the strong forces that bind them together and allow them to flow off into solution as solvated ions.
Hence option B is correct.

Note:
An ionic compound is a chemical complex made up of ions kept together by electrostatic forces known as ionic bonding in chemistry. Overall, the molecule is neutral, although it contains both positively and negatively charged ions known as cations and anions.
