The number of white coloured salts among the following is ....... $A: SrSO_{4}$ $B: Mg(NH_{4})PO_{4}$ $C: BaCrO_{4}$ $D: Mn(OH)_{2}$ $E: PbSO_{4}$ $F: PbCrO_{4}$ $G: AgBr$ $H: PbI_{2}$ $I: CaC_{2}O_{4}$ $J: Fe(OH)_{2}(CH_{3}COO)$

Question

Aicharya · Accepted Answer

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 $5$ .
