What happen if you incomplete drying of the PbCrO4 residue prior to final weighing in experiment?
If the PbCrO4 residue is not completely dried before final weighing, it will contain residual moisture which can lead to an inaccurate measurement of the compound's weight. This can affect the reliability and precision of the experimental results. It is important to ensure that the residue is completely dry to obtain accurate and reproducible measurements.
What else can I help you with?
Is PbCrO4 soluble?
PbCrO4 is insoluble in water, meaning it does not dissolve well in water.
What is the chemical formula of lead II chromate?

PbCrO4 is the chemical formula for lead(II) chromate, a yellow-colored compound commonly used as a pigment in paints. It is sparingly soluble in water and is toxic if ingested or inhaled.
What is the formula for the compound formed by lead II and chromate ions?
The compound formed by lead (II) and chromate ions is lead(II) chromate, with the chemical formula PbCrO4.
What is the formula for leadII chromate?
Lead(II) Chromate = PbCrO4
What addition to a saturated solution of PbCrO4 leads to the common ion effect?
Adding Pb2+ ions to a saturated solution of PbCrO4 would lead to the common ion effect. The additional Pb2+ ions would increase the concentration of the common ion in the solution, shifting the equilibrium to the left and causing more PbCrO4 to precipitate out of the solution.
