The reactive species in chlorine bleach is
- A \(\mathrm{Cl}_{2} \mathrm{O}\)
- B \(\mathrm{OCl}^{-}\)
- C \(\mathrm{Cl} \mathrm{O}_{2}\)
- D \(\mathrm{HCl}\)
Answer & Solution
Correct Answer
(B) \(\mathrm{OCl}^{-}\)
Step-by-step Solution
Detailed explanation
Chlorine bleach is \(\mathrm{NaOCl}\). The hypochlorite ion in chlorine bleach dissociates to give nascent oxygen as shown below. \[ \mathrm{OCl}^{-} \longrightarrow[\mathrm{O}]+\mathrm{Cl}^{-} \] Therefore, the reactive species in chlorine bleach is \(\mathrm{OCl}^{-}\) So, the…
