Question

Define insoluble salts.

• A. Insoluble salts are the compounds which readily dissolve in water.
• B. Insoluble salts are the compounds which do not readily dissolves in water.
• C. Insoluble salts are the salts that are formed by mixing of two simple salts
• D. Insoluble salts are the salts that contain a definite number of water molecules as water of crystallization

Answer 1

The correct option is B Insoluble salts are the compounds which do not readily dissolves in water.

$\left(B\right)$ Insoluble salts are the compounds which do not readily dissolves in water.

$Reason$ : Insoluble salts are those ionic compounds that are not able to dissolve in water but form a suspension,i.e., the salt continues to exist as a solid rather than dissolving in liquid. As polar and non-polar substances are insoluble when mixed with each other.

$For$ $example$ - All carbonates($C{O}_3$) , hydroxides($OH$) and oxides($O$) are insoluble with the exception of sodium, potassium and ammonium salts

$Note$ : Separation of insoluble components in a mixture is easier than separating soluble components..
