Silver ion Reactions: 1. where the products are calcium carbonate and sodium chloride. Calculate the mass of precipitate produced in the reaction. Large natural deposits found in 1938, such as the one near Green River, Wyoming, have made mining more economical than industrial production in North America. Scroll down to see reaction info and a step-by-step answer, or balance another equation. K_{SP} for Ag_2CO_3 is 8.46 times 10^{-12}. It is one of the few metal carbonates that is soluble in water. Second, consult the solubility rules to determine if the products are soluble. (Na2CO3) and form calcium carbonate (CaCO3) and Na2CO3 + HCl + Ca(NO3)2 = NaCl + CaCl2 + H2O + CO2 + HNO3, Na2CO3 + HCl + Ca(NO3)2 = NaNO3 + CaCl2 + H2O + CO2, Na2CO3 + HCl + Ca(OH) = NaOH + CaCO3 + HCl, Na2CO3 + HCl + Ca(OH)2 = NaCl + H2O + CaCO3, Na2CO3 + HCl + CaCO3 = NaCl + CO2 + H2O + CaO, Na2CO3 + HCl + CaCO3 = NaCl + H2O + CaCO3, Na2CO3 + HCl + CaN2O6 = NaCl + CaCl2 + H2O + CO2 + HNO3. What is the formula of the precipitate formed from the precipitation reaction of Pb(NO_3)_2 and NaI? What is that precipitate? Show Stills, Here, sodium carbonate (Na2CO3) is added to cadmium nitrate (Cd(NO3)2). The balanced equation will appear above. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. If so, write the ions present in the solution. Learn about solubility equilibrium, solubility units, and the various factors that affect solubility.
