Chemistry · Chemical principles involved in experiments: Enthalpy of solution of CuSO4, Enthalpy of neutralization of strong acid and strong base, Preparation of lyophilic and lyophobic sols, Kinetic study of the reaction of iodide ions with hydrogen peroxide at room temperature

sol is :

\( \boldsymbol{A} \boldsymbol{s}_{2} \boldsymbol{S}_{3} \) sol is :

  • A. positive colloid
  • B. negative colloid
  • C. neutral colloid
  • D. none of the above

Step-by-step solution

As2S3 sol is typically negatively charged because the particles preferentially adsorb S2- ions from the dissociation of H2S, giving it a negative charge. This is a common property of many metal sulfide sols.
