Formation of Sodium Hydroxide and Potassium Hydroxide: When a small piece of Na is added to a solution containing an indicator, evidence of the reaction can be observed by the change in the color of the solution as NaOH is formed, by the melting of the Na and by the movement of the Na caused by formation of hydrogen gas. Precipitate. But if sodium hydroxide is added into a solution of copper ions, it would form Copper(II) Hydroxide. What Is The Chemical Equation For Cobalt Chloride And Sodium Hydroxide? Since zinc sulfide is insoluble in water, it can also be produced in a precipitation reaction. This involves deprotonation of two of the water ligand molecules: 18.4 Precipitation reactions (ESAFR) Sometimes, ions in solution may react with each other to form a new substance that is insoluble. Iron filings, copper sulphate solution, magnesium ribbon, zinc granules, dilute sulphuric acid, sodium sulphate and barium chloride solutions and copper sulphate .
