Q13.88P - Chemistry: Molecular Nature Of Matter And Change

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)

Step-by-Step Solution

Answer

Answer

 

(a) Hydrogen chloride$\left(HCl\right)$ is strong 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 1: HCl

 

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

 

Step 2: KNO 3

 

KNO₃ is a strong electrolyte because it almost completely ionizes or dissociates in a solution. Electricity flows well through it.

Step 3: C 6 H 12 O 6

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: NH 3

 

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