What happens when potassium dichromate reacts with stannous chloride

Answer 1

reaction of potassium dichromate with stannous chloride is listed above.

Answer 2

When potassium dichromate (K2Cr2O7) reacts with stannous chloride (SnCl2), a redox reaction occurs, and the products depend on the conditions of the reaction.

Here is one possible reaction that could occur:

K2Cr2O7 + 6 SnCl2 + 14 HCl → 3 SnCl4 + 2 CrCl3 + 2 KCl + 7 H2O

In this reaction,

The potassium dichromate is reduced to chromium(III) chloride (CrCl3), while the stannous chloride is oxidized to stannic chloride (SnCl4).

The reaction also produces potassium chloride (KCl) and water (H2O).

The reaction is often used as a qualitative test for the presence of chloride ions (Cl-) in a solution.

When stannous chloride is added to a solution containing chloride ions, it forms stannic chloride, which is a white precipitate.

The addition of potassium dichromate to this solution then oxidizes the stannous chloride back to stannic chloride,

Which reacts with the remaining chloride ions to form a red-brown solution of SnCl4.

The color change from white to red-brown indicates the presence of chloride ions in the solution.
