Question

Which of the following statement is correct?

• A. F₂ oxidises H₂O to O₂ but Cl₂ does not.
• B. Fluoride is a good oxidizing agent.
• C. Cl₂ oxidises H₂O to O₂ but F₂ does not.
• D. Cl₂ is a stronger oxidizing agent than F₂ .

Answer 1

Answer: (A)

$2F_{2\left(g\right)}+2H_{2}O_{l} \to4H_{\left(aq\right)}^{+}+4F_{\left(aq\right)}^{-}+O_{2\left(g\right)}$
$X_{2\left(g\right)}+H_{2}O_{\left(l\right)} \to HX_{\left(a q\right)}+HOX_{\left(aq\right)}$
$X=Cl_{2} \, or \, Br_{2}$
