Show Answer
Answer (5)
Solution
$\mathrm{SrSO}_{4}$ - white
$\mathrm{Mg}\left(\mathrm{NH}{4}\right) \mathrm{PO}{4}$ - white
$\mathrm{BaCrO}_{4}$ - yellow
$\mathrm{Mn}(\mathrm{OH})_{2}$ - white
$\mathrm{PbSO}_{4}$ - white
$\mathrm{PbCrO}_{4}$ - yellow
$\mathrm{AgBr}$ - pale yellow
$\mathrm{PbI}_{2}$ - yellow
$\mathrm{CaC}{2} \mathrm{O}{4}$ - white
$\left[\mathrm{Fe}(\mathrm{OH}){2}\left(\mathrm{CH}{3} \mathrm{COO}\right)\right]-$ Brown Red
