WebJan 31, 2024 · And this is essentially the [$\ce{Cr^3+}$] and [$\ce{Cr(OH)4-}$]. However, this is not what the book says. They meant to put the concentration of $\ce{Cr(OH)4-}$ as .010 M, not $\ce{Cr^3+}$. Let's try it that way, and see what we get! Cr(OH)4- <=> Cr3+ + 4OH-Here, in the equation, the concentrations are: $\ce{Cr(OH)4-}$ = .010 M …

WebAnswer (1 of 2): For my way of thinking, it’s probably best to see how the oxidation states of each element individually change before and after reaction. To make it simpler, think about which elements would have known oxidation states, e.g. oxygen, unless it’s elemental (O2, O3, oxidation numbe... WebFollow.

WebThe average oxidation state of the sulfur atoms is therefore +2 1 / 2. STEP 3: Determine which atoms are oxidized and which are reduced. STEP 4: Divide the reaction into oxidation and reduction half-reactions and balance these half-reactions one at a time. This reaction can be arbitrarily divided into two half-reactions. crunchies dried fruit
