Web2 days ago · CaCO 3 + 2 HCl = CaCl 2 + CO 2 + H 2 O Now that there is an equal quantity of Ca, C, Cl, H and O on both sides, the chemical equation is balanced. Even though it was simple, there are actually quite a few cases where you can balance the chemical equation in one step: Iron + Hydrogen Chloride = Ferrous Chloride + Hydrogen Gas: Fe + HCl → … WebTo find the correct oxidation state of Cr in CrO4 2- (the Chromate ion), and each element in the ion, we use a few rules and some simple math.First, since th...
WebIn acid solution the aquated Cr 3+ ion is produced. Cr 2O2− 7 + 14 H + + 6 e − → 2 Cr 3+ + 7 H 2 O ε0 = 1.33 V In alkaline solution chromium (III) hydroxide is produced. The redox potential shows that chromates are weaker oxidizing agent in alkaline solution than in acid solution.
