When negatively charged colloids like As_(2)S_(3) sol is added to positively charged Fe(OH)_(3) sol in suitable amounts

When negatively charged colloids like As_(2)S_(3) sol is added to positively charged Fe(OH)_(3) sol in suitable amounts :

A : Al^(+3) can be used for the cagulation of As_(2) S_(3) sol . R : Al^(+3) reacts with As_(2)S_(3) "to give" Al_(2) S_(3)

Statements : A yeellow colured As_2S_3 sol on mixing with red colured Fe(OH)_3 sol gives colsurless soltion . Expabnations : The -ve charge os As_2S_3 sol particles is neutralised by + ve charge of Fe(OH)_3 sol particles and thus sols are destabilized and show mutual coagulation .
