Correct answer
5

Step-by-step explanation

The colour of the salts are as follows,

SrSO4- white
MgNH4PO4 - white
BaCrO4 - yellow
Mn(OH)2 - white
PbSO4 - white
PbCrO4 - yellow
AgBr - pale yellow
PbI2 - yellow
CaC2O4 - white

Fe(OH)2CH3COO – Brown Red

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