Question

Question: Classify the following substances as strong electrolytes, weak electrolytes, or non-electrolytes:

(a) Hydrogen chloride (HCl)

(b) Potassium nitrate (KNO3)

(c) Glucose (C6H12O6)

(d) Ammonia (NH3)

Short answer

Answer

(a) Hydrogen chloride$\left(HCl\right)$isstrong electrolyte

(b) Potassium nitrate$\left(KN{O}_3\right)$is strong electrolyte

(c) Glucose$\left(C_6{H}_{12}{O}_6\right)$is non electrolyte

(d) Ammonia$\left(N{H}_3\right)$is weak electrolyte

Step-by-step solution

HCl

HCl is a strong electrolytebecause it almost completely ionizes or dissociates in a solution. It effectively conducts electricity.

 KNO3

KNO₃is a strong electrolyte because it almost completely ionizes or dissociates in a solution. Electricity flows well through it.

C6H12O6 

Glucose is a non-electrolyte because it does not have any distinct ionic form and do not ionize in a solution. They are poor conductor of electricity.

Step 4:  NH3

Ammonia is a weak electrolytebecause it only partially ionizes in a solution. They are weak conductor of electricity.
