MHT CET Chemistry Question (2026) — Solution

Step-by-step solution

Electrical conductivity of an aqueous solution depends on the number of ions present and their ionic mobility. HCl is a strong electrolyte and dissociates completely in water to give H ^+ and Cl ^- ions. CH _3 COOH and NH _4 OH are weak electrolytes and dissociate only partially, producing fewer ions. C _6 H _ 12 O _6 (glucose) is a non-electrolyte and does not dissociate into ions. Furthermore, the H ^+ ion has exceptionally high ionic mobility in water. Thus, the equimolar solution of HCl has the highest concentration of highly mobile ions, making it the best conductor of electricity.
