The chemical formula of lead sulphate is:
|
|
Pb2SO4
|
|
|
Pb(SO4)2
|
|
|
PbSO4
|
|
|
Pb2(SO4)3
|
Explanation:
Detailed explanation-1: -Pb2(SO4)3? Explanation: PbSO4 (lead(II) sulphate) is a white solid with a microcrystalline appearance. Fast white, milk white, sulfuric acid lead salt, or anglesite are some of the other names for it.
Detailed explanation-2: -The Chemical Formula of Lead Sulfate is (A) Pb2SO4 (B) Pb(SO4)2 (C) PbSO4 (D) Pb2(SO4)3.
Detailed explanation-3: -The PbSO4(PbO)4 QDs significantly reduce the defect density of the as-prepared CH3NH3PbI3 films by passivating under-coordinated Pb ions and I anions and effectively enhance charge extraction efficiency at the TiO2/CH3NH3PbI3 and CH3NH3PbI3/spiro-OMeTAD interfaces.
