Question

which of the following compounds is a strong electrolyte?
h₂o
ch₃oh
ch₃ch₂oh
hf
naf

Explanation:

A strong electrolyte completely dissociates into ions in solution. Water ($H_2O$) is a weak electrolyte and a solvent. Methanol ($CH_3OH$) and ethanol ($CH_3CH_2OH$) are non - electrolytes as they do not dissociate into ions in solution. Hydrofluoric acid ($HF$) is a weak electrolyte as it only partially dissociates. Sodium fluoride ($NaF$) is an ionic compound and completely dissociates into $Na^+$ and $F^-$ ions in solution, making it a strong electrolyte.

Answer:

NaF
