Question

In which of the following solutions, ions are present
A. Sucrose in water
B. Sulphur in \[C{S_2}\]
C. Caesium nitrate in water
D. Ethanol in water

Answer 1

Hint: Any ionic compound's constituent particles are called ions. Ionic compounds have the capacity to separate into their individual ions in solutions. Their aqueous solution can transmit electricity due to this dissociation.

Complete step-by-step answer:In order to know that how an ionic compound is created, electrons from a metal are transferred to a non-metal to create ionic connections.

These substances can dissolve in many solution, including polar solutions like water. These compounds split apart into their corresponding ions as a result of dissolving.
The salt caesium nitrate has the chemical formula \[CsN{O_3}\]. It is a crystalline substance that sparkles and is colourless. It is water soluble.

Caesium's electron configuration is \[[Xe]\,6s^1\]. There are \[ + 1\] potential oxidation states.
Caesium nitrate when dissolved in water dissociates into caesium ion and nitrate ion. On the other hand Sucrose, sulphur, and ethanol are not ionic compounds as caesium nitrate.
Therefore, the ions present in the solution of caesium nitrate in water except for others.

Option ‘C’ is correct

Note: Covalent molecules such as sucrose, ethanol do not form in ions when dissolved in water. These compounds are soluble in water due to the formation of hydrogen bonds. These compounds have -OH groups in it which helps in Hydrogen bond formation with water molecules.
