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

Step-by-step solution

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 .
