Question

When CO gas is passed through palladium chloride solution, the solution turns​

Answer 1

Explanation:

Palladium(II) chloride, also known as palladium dichloride and palladous chloride, are the chemical compounds with the formula PdCl2. PdCl2 is a common starting material in palladium chemistry – palladium-based catalysts are of particular value in organic synthesis. It is prepared by the reaction of chlorine with palladium metal at high temperatures.

Palladium(II) chloride

Answer 2

When CO gas is passed through palladium chloride solution, the solution turns​ red.

Explanation:

• Carbon monoxide reduces palladium(II) chloride to palladium. $PdCl2 + CO + H2O ---Pd + CO2 + 2HCl.$

• Carbon monoxide reduces palladium(II) chloride to palladium and turns the solution red.

• Palladium(II) chloride is used widely in carbon monoxide detectors.
• Residual$PdCl2$ is converted to red$PdI2,$
• The concentration will be determined colorimetrically.
• $PdCl2 + 2 KI---------PdI2 + 2 KCl$
• Palladium chloride is used for the manufacture of aldehydes.
