Question

The number of white coloured salts among the following is ....... A SrSO 4 B Mg NH 4 PO 4 C BaCrO 4 D Mn ( OH ) 2 E PbSO 4 F PbCrO 4 G AgBr H PbI 2 I CaC 2 O 4 J Fe ( OH ) 2 CH 3 COO

The colour of the salts are as follows,

${SrSO}_{4}$ - white
$Mg ({NH}_{4}) {PO}_{4}$ - white
${BaCrO}_{4}$ - yellow
$Mn (OH)_{2}$ - white
${PbSO}_{4}$ - white
${PbCrO}_{4}$ - yellow
$AgBr$ - pale yellow
${PbI}_{2}$ - yellow
${CaC}_{2} O_{4}$ - white

$[Fe (OH)_{2} ({CH}_{3} COO)]$ – Brown Red

Hence the number of salts which are white in colour is $5$ .
