H3PO3(aq) mc032-1.jpg H+(aq) + H2PO3–(aq) CH3CH2COOH(aq) + H2O(l) mc032-2.jpg H3O+(aq) + CH3CH2COO–(aq) CH3CH2OH(l) mc032-3.jpg CH3CH2OH(aq) Ca(NO3)2(s) mc032-4.jpg Ca2+(aq) + 2NO3–(aq) Solve problem with AI  Answer: The correct answer is $$Ca(NO_3)_2(s)\rightarrow Ca^{2+}(aq.)+2NO_3^-(aq.)$$

Explanation:

A strong electrolyte is defined as the electrolyte which completely dissociates into its ions when dissolved in water.

A weak electrolyte is defined as the electrolyte which does not completely dissociates into its ions when dissolved in water.

A solution having more number of ions will easily conduct electricity.

For the given chemical equations:

1. $$H_3PO_3(aq.)\rightarrow H^+(aq.)+H_2PO_3^-(aq.)$$

It is a weak electrolyte because it is not completely dissociated and number of ions present are 2.

2. $$CH_3CH_2COOH(aq.)+H_2O(l)\rightarrow H_3O+(aq.)+CH_3CH_2COO^-(aq.)$$

It is a weak electrolyte because it is not completely dissociated and number of ions present are 2.

3. $$CH_3CH_2OH(l)\rightarrow CH_3CH_2OH(aq.)$$

Here, hydration of ethanol is taking place and no ions are present in the solution.

4. $$Ca(NO_3)_2(s)\rightarrow Ca^{2+}(aq.)+2NO_3^-(aq.)$$

It is a strong electrolyte because it is has completely dissociated into its ions and number of ions present are 3 and thus it will conduct electricity.

Therefore, the solution which will conduct electricity extremely well will be $$Ca(NO_3)_2(s)\rightarrow Ca^{2+}(aq.)+2NO_3^-(aq.)$$
