1) John should make his shirts cold water. becuase forward reaction is exothermic . so exothermic reactions are favourable at low temperatures . so to get more color low temperature must be used
2) help ;
at high pH [Fe(CN)6]3– fromation decreases because cojugate base CN- readily react with Na+ speciecs present in base . so the availability of CN - decreases
3) low pH the smell due to
