Which of the following are strong electrolytes? hcl hc2h3o2 nh3 kcl

THIS IS THE BEST ANSWER 👇

Answer;

HCl and KCl

Explanation; Strong electrolytes are strong bases and acids. HCl is a strong acid; it dissolves completely to form H + and Cl- ions. So it is a strong rather than weak electrolyte. CH3COOH is an acetic acid, a weak acid. Only some of it will decompose (to H + ions and acetate), therefore it will only be a weak electrolyte. N3 reacts with water as a weak base: NH3 + H2O → NH4 + + OH-. So it will also be a weak electrolyte. KCl is a soluble ionic compound, and will therefore form a strong electrolyte.
