A) AgCl

B) CaSO4

C) CaC2O4

D KCLO4

E) None of these​

Answer 1

option (E) none of these

Answer 2

Answer:

E) None of these​

Explanation:

TO FIND: Not an example of sparingly soluble salt from the following.

A) AgCl is sparingly soluble salt.

B) CaSO4  is sparingly soluble salt.

C) CaC2O4   is sparingly soluble salt.

D KCLO4 (Potassium perchlorate)   is sparingly soluble salt.

E) None of these​

Sparingly soluble materials are those, which have lowered solubility.

Usually materials are treated as sparingly soluble if 1g of material requires 30 to 100ml of solute to dissolve.

A sparingly soluble salt is so-called because when it is stirred into water or mixed with water, only a very small amount of the salt goes into the solution, and most of it remains undissolved.

A material will be sparingly soluble if the amount which can be dissolved in 100ml of solute ranges between 1g and 3,3g.

Calcium oxalate monohydrate [Ca(O2CCO2)·H2O, also written as CaC2O4·H2O] is a sparingly soluble salt that is the other major component of kidney stones.

The solution becomes saturated with that little amount of salt dissolved, and the salt immediately dissociates into its ions.

Ca(OH)2 is only slightly soluble in  water at 20°C forming a basic solution called lime water.
