Question

which of the following molecules is not an electrolyte?
a na+
b k+
c cl-
d h2o

Explanation:

Electrolytes are substances that dissociate into ions in solution. \(Na^{+}\), \(K^{+}\), and \(Cl^{-}\) are ions. \(H_{2}O\) (water) is a covalent compound and does not dissociate into ions to a significant extent to be considered a strong electrolyte.

Answer:

D. \(H_{2}O\)
