Question

How will you make a saturated solution of KI?
(Saturated solution of potassium iodide).

Answer 1

Hint: In this question we have to make a saturated solution of potassium iodide first we will have to explain saturated solution.
A solution that contains the maximum amount of solute which is capable for dissolution, at the particular temperature.

Complete step by step answer:
In the case of saturated solution of potassium iodide in water at room temperature is about \[1.40-1.48\]grams/millilitre pure water.
We are taking an simple reaction when potassium iodide will breaks into ions then
Reaction explanation:-
\[KI\to {{K}^{+}}+{{I}^{-}}\] or \[KI\rightleftharpoons {{K}^{+}}+{{I}^{-}}\]
Above we have simple ionic reaction here we have potassium iodide breaks into potassium positive \[\left( {{k}^{+}} \right)\] and iodine negative \[\left( {{I}^{-}} \right)\] ion.
When we mix an appropriate amount of potassium iodide then we have saturated solution of potassium iodide, but when the we mix \[\phi \] more than sufficient amount then reversible reaction will takes place then again the ions will get attached to each other when as a result we have precipitation formation on the upper layer of the solution because in reversible process again potassium iodide in real form will not form.
At this stage the solution will be unsaturated.
Hence at room temperature \[1.40\] grams of potassium iodide required for millilitre of pure water for saturated solution of any compound in water or in any liquid material solubility of the ions must be important in that solution.
If solubility of compounds is more, the solution will be saturated. But when solubility is saturated. But when solubility becomes much more than precipitation will form.

Note: Meaning of saturation is completely dissolution of concentration of solute in the given solvent before making the solution first we have knowledge of the solubility of solute in the given solvent. Here potassium iodide can make a solution here potassium iodide can make a solution with water, alcohol and mere solvents with a given concentration of solvent.
