Answer:
Ba(OH)2 is a strong base, so it conducts electricity well
Explanation:
The dissociation of a strong electrolyte is apparent by its reaction arrow, which only points toward products. In contrast, the reaction arrow of weak electrolytes points in both directions. The general form of the strong electrolyte equation is: Strong acids, strong bases, and ionic salts that are not weak acids or bases are strong electrolytes.
X NH3 is a weak base
X C12H22011 is neutral (not an acid or a base), therefore it a nonelectrolyte
X CH3COOH is a weak acid and it also dissociates partially.
The substance which is a strong electrolyte is Ba(OH)₂.
Hence Option (B) is correct answer.
What is Strong electrolyte ?
Strong electrolyte can be defined as the substance that completely dissociates in to ions.
Strong electrolyte (aq) → cation⁺ (aq) + anion⁻ (aq)
Now lets check all options one by one
Option (A): NH₃
NH₃ is a weak base. NH₃ does not completely ionize so it is a weak electrolyte.
Hence it is incorrect option.
Option (B): Ba(OH)₂
Ba(OH)₂ is a strong electrolyte because it dissociates completely in water.
Ba(OH)₂ (aq) → Ba⁺² (aq) + 2OH⁻ (aq)
Hence, it is correct option.
Option (C): C₁₂H₂₂O₁₁
C₁₂H₂₂O₁₁ is a non electrolyte that means it does not dissociate into ions.
Hence, it is incorrect option.
Option (D): CH₃COOH
CH₃COOH is a weak electrolyte due to the presence of lowest number of ions it does not dissociate. It's ionization is very less.
Hence, it is incorrect option.
Thus, from the above conclusion we can say that The substance which is a strong electrolyte is Ba(OH)₂.
Hence Option (B) is correct answer.
