Dichromate reaction
WebAug 18, 2024 · A precipitation reaction is a reaction that yields an insoluble product—a precipitate—when two solutions are mixed. We described a precipitation reaction in which a colorless solution of silver nitrate was mixed with a yellow-orange solution of potassium dichromate to give a reddish precipitate of silver dichromate: WebExercise 13.4. 1. Write an equation for the oxidation of each alcohol. Use [O] above the arrow to indicate an oxidizing agent. If no reaction occurs, write “no reaction” after the arrow. From left to right, there are six carbons on the alkane straight chain with a hydroxyl group and methyl group on carbon 3.
