WebSilver chloride is insoluble in water and form a white color precipitate in water. If it is explained in other way, you can see a white color solid is deposited at the bottom of the aqueous solution. You can verify AgCl's solubility by checking its solubility value and solubility product value. When solubility and solubility product are too ... WebDec 1, 2024 · 2.1. Synthesis of silver cyanide (AgCN) from silver nitrate (AgNO 3) In a typical procedure, 10 mg of V 2 O 5 was dissolved in 1.5 mL of H 2 O 2. To the resulting yellow solution, 10 mL of CH 3 CN was added and the reaction mixture was stirred at room temperature for 30–45 min. The colour of the solution at this stage was found to be red. WebOne technique for minimizing these problems is to remove the mother liquor, re-dissolve the precipitate and then re-precipitate. The second time the mother liquor will contain fewer unwanted ions capable of co-precipitation. Conditions of Precipitation: 1. Precipitation should be carried out in dilute solutions. 2. chinyereododo
