WebbProcess for the production of Prussian blue by reacting sodium ferrocyanide with iron (II) salts to form a precipitate of a ferrocyanic acid salt, which is treated with a potassium … Webb4. Predict whether a precipitate will form as a result of this reaction: (1) 2 A g N O 3 + N a 2 S → A g 2 S + 2 N a N O 3. The products of the reaction must be examined; if either of the substances formed in the reaction is insoluble, a precipitate will form. Considering NaNO 3, Rule #3 states that nitrates tend to be soluble.
