Webdichromate: [noun] a usually orange to red chromium salt containing the anion Cr2O72− — called also#R##N# bichromate. WebDichromate definition, a salt of the hypothetical acid H2Cr2O7, as potassium dichromate, K2Cr2O7. See more.
Dichromate reduction half equation
Did you know?
WebThe balanced equation for the reaction is: 6Fe2+ (aq) + Cr2O7-2 (aq) + 14H+ (aq) → 6Fe3+ (aq) + 2Cr3+ (aq) + 7H2O (l) From the balanced equation, we see that 6 moles of Fe2+ react with 1 mole of Cr2O7-2. The volume of the potassium dichromate solution used is not given in the question. So, we need to calculate it first.
