Question

The molar solubility of __________ is not affected by the ph of the solution.a) ca3(po4)2

b.mnsc) mgf2d) mg(oh)2e) kno3

Answer 1

The correct answer is e.

Step-by-step explanation:

KNO3 ions are neither acidic nor basic. The KNO3 composition salt is formed from the reaction of a strong acid (HNO3) and a strong base (KOH). The ions that act in the formation of the compound cannot lose or gain protons. This means that the molar solubility is not affected by the pH of the solution. The aqueous solution is almost neutral.

Have a nice day!

Answer 2

The molar solubility of KNO3 is not affected by the PH of the solution.


This is because KNO3 ions are either acidic or basic.KNO3 salt is formed from the reaction of strong acid HNO3 and a strong base KOH and neither the potassium ion nor the nitrate ions can either lose, gain protons or hydrogen ions.
