Question

is BaCrO4 soluble or insoluble and why ?

Answer 1

It is very insoluble in water, but is soluble in acids: 2 BaCrO4 + 2 H+ → 2 Ba2+ + Cr2O72− + H2O.

Answer 2

$BaCrO4$ is  insoluble in water and soluble in acids.

Explanation:

• $BaCrO4$ is very insoluble in water, but is soluble in acids
• $2BaCrO4 + 2 H^{+} ------- 2Ba^{2+} + Cr2O7^{2-} + H2O.$
• Barium chromate also named barium tetra oxochromate(VI) according to  IUPAC
• It is yellow sand like powder.
• It has the formula $BaCrO4$.
• It is also known as oxidizing agent.
• It produces a green flame when heated, a result of the barium ions.
• It is used as a corrosion inhibitive pigment when used in zinc-alloy electroplating surfaces.
• It is also used as a catalyst for alkane dehydrogenation.
