You probably mean lead chromate since you have mentioned an oxidation state of 2+ for the lead ion and the chromate ion has an oxidation state of 2-.
Lead chromate is yellow. Please see the link.
Two possibilities:
Only of Lead(II) chromate PbCrO4 (not the one asked, though) I know the color because it is known as Chroom Yellow, used in paints. And also Iron(III) chromate Fe2(CrO4)3 is yellow
As lead can have more than one valence the formual for Lead II Chromate is PbCrO4
PbCrO4
PbCrO4
Its Colorless
It has a white color in the form of powder of cyrstals : )
NiCr 2 O 7
Lead compounds tend to be blue in flame tests
A White precipitate would be obtained.
The chemical name for PbCr2O7 is lead dichromate.
The chemical name of SnCr2O7 is tin(IV) dichromate.
H2Cr207 is also known as chromic acid.
It is Ferrous chromate or Iron (II) chromate .
The oxidation number for lead in lead(IV) dichromate is +4, while the oxidation number for chromium in dichromate is +6.
Lead(II) iodide has at room temperature a pretty yellow color.
Lead(II) iodide is yellow in colour
Lead (II) azide has the molecular formula of Pb(N3)2. Lead (II) azide has the molecular weight of 291.2 grams per mole.
Its Colorless
Lead (II) carbonate is typically white in color.
Its Colorless
It has a white color in the form of powder of cyrstals : )
