which substance is a strong electrolyte?\no nh₃\no ba(oh)₂\no c₁₂h₂₂o₁₁\no ch₃cooh
which substance is a strong electrolyte?\no nh₃\no ba(oh)₂\no c₁₂h₂₂o₁₁\no ch₃cooh
Answer
Explanation:
Step1: Recall strong - electrolyte definition
Strong electrolytes completely dissociate in solution.
Step2: Analyze each option
- $NH_3$ is a weak base and a weak electrolyte. It only partially ionizes in water: $NH_3 + H_2O\rightleftharpoons NH_4^++OH^-$.
- $Ba(OH)_2$ is a strong base. It completely dissociates in water as $Ba(OH)_2\rightarrow Ba^{2 +}+2OH^-$, so it is a strong electrolyte.
- $C_{12}H_{22}O_{11}$ (sucrose) is a non - electrolyte. It does not dissociate into ions in solution.
- $CH_3COOH$ is a weak acid. It only partially ionizes in water: $CH_3COOH\rightleftharpoons CH_3COO^- + H^+$.
Answer:
$Ba(OH)_2$
