Aqueous solution of conducts electricity due to the presence of:
Aqueous solution of \( \mathrm{PBr}_{3} \) conducts electricity due to the presence of:
- A. \) HOBr
- B. НВг
- C. \( \mathrm{H}_{3} \mathrm{PO}_{4} \)
- D. \( \mathrm{H}_{2} \mathrm{O} \)
Step-by-step solution
PBr3 hydrolyzes in water to form H3PO3 and HBr: PBr3 + 3H2O → H3PO3 + 3HBr. HBr is a strong acid that dissociates completely into H+ and Br- ions, providing electrical conductivity. H3PO3 is a weak acid and contributes less; H2O and HOBr are not responsible for significant conductivity.
