Wich of the following are redox reactions? For those that are, indicate wich element is oxidized and wich is reduced. For those that are not indicate whether they are precipitation or neutralisation reaction. D) ZnCl2(aq) +2NaOH—>Zn(OH)2+2NACl(aq)

When cations and anions in an aqueous solution react to generate a precipitate, an insoluble ionic solid, a precipitation reaction takes place. The solubility principles for typical ionic solids can be used to determine whether or not such a reaction takes place. Before figuring out the condition of the products and creating a net ionic equation, one must refer to the solubility criteria because not all aqueous reactions produce precipitates.

Single replacement reactions or double replacement reactions make up the majority of precipitation reactions. Depending on whether they are a cation or an anion, the ions swap places. When the chemical equation in issue takes place in an aqueous solution and one of the products generated is insoluble, the reaction is particularly categorized as a precipitation reaction.
