In acidic medium chromate ion converts to dichromate ion as: underset text Yellow 2 CrO 42-+2 H + longrightarrow underset text Orange Cr 2 O 72-+ H 2 O

Q. The colour of potassium dichromate depends upon $p H$ of solution. The chromate and dichromate are interconvertible in aqueous solution depending upon $p H$ . In acidic $p H$ , chromate ions get converted into ions whose colour is

blue

orange

red

colourless.

In acidic medium chromate ion converts to dichromate ion as :

$Yellow 2 C r O_{4}^{2 -} + 2 H^{+} ⟶ Orange C r_{2} O_{7}^{2 -} + H_{2} O$
