Web5.0 (3 reviews) Term. 1 / 123. bonds to the central atom are covalent. If the central atom can form covalent bonds to the hydroxyl groups, these bonds will be difficult to cleave, and the O−H bond will be more likely broken in an acid-base reaction. This would make the compound a proton donor and therefore an acid. Click the card to flip 👆. WebThis is written as Ag+ + e- → Ag. As electrons are gained, the silver ion is reduced. The strongest oxidation half-reaction that could occur is the oxidation of the sulfite ion (S2O3^2-) to the sulfate ion (SO4^2-). This is written as S2O3^2- → SO4^2- + 2e-. As electrons are lost, the sulfite ion is oxidized. the postman movie reviews

Webthe sum of all the oxidation numbers in a neutral compound = 0. the sum of all the oxidation numbers in a polyatomic ion = the charge of the ion. In the case of S2O3^2- (I presume you missed the 2 there), this means: 2 x ON (S) + 3 x ON (O) = —2. Since the ON of oxygen in a compound is usually —2, this yields, 2 x ON (S) + 3 x (—2) = —2 ... WebSuppose that you add a small and known amount of thiosulfate ion to the original mixture of peroxide and iodide.
