Question

Which one of the following solutions will have highest conductivity?

• A. $0.1MC{H}_{3}COOH$
• B. $0.1MNaCl$
• C. $0.1MKN{O}_3$
• D. $0.1MHCl$

Answer 1

Answer: (D)

$HCl$ and $KN{O}_3$ both are strong electrolyte but $HCl$ have aqueous component $H^{+}$, which has highest conductivity.
$\therefore HCl$ will have highest conductivity.
