A salt does not release ______ in water.

a. ions b. H +

Summary Introduction

Introduction:

The “polarity” of water molecules and the ability to form hydrogen bonds enables water to dissolve many substances. Hydrophilic substances dissolve easily in water. Ionic solids, such as sodium chloride, are hydrophilic. Many nonionic solids, such as sugar, are also hydrophilic. Water does not interact with hydrophobic substances.

Explanation of Solution

Reason for correct answer:

Option b. is given as “H+”.

Salts are ionic compounds made up of two groups of oppositely charged ions. They contain positive ions from metal and negative ions from non-metal. Metals form cation by losing electrons and non-metals gain electron to form anion. These ions attract each other to form salt. Ions are bonded to each other by an ionic bond. When a salt is dissolved in water, ions are released. Therefore, salt does not release H+ when dissolved in water.

Reason for incorrect answer:

Option a
