Question

Question 6120 points 1. During a metathesis reaction, three chemical processes can result in the removal of ions from solution. these is the formation of a precipitate. Give the other two. (4 points] When cadmium chloride, CdClz reacts with sodium sulfide, Na S, a yellow precipitate forms. Write the balanced molecular, ionic and net ionic equations for this reaction and identify the yellow precipitate. Use the information in the table below as a guide in determining the reaction products Water-soluble Ct Salts All chlorides are soluble except those of silver, lead(II) and mercury(l) All salts are soluble except those of silver, mercury and lead. Na', K All salts of sodium and potassium are soluble All sulfates are soluble except those of calcium, barium, strontium, mercury lead and silver. so.2 All sulfides are insoluble except those of the alkali metals (Group 1A), alkaline earth metals (Group 2A) and NH Water-insoluble S Salts All carbonates and phosphates are insoluble except those of alkali metals and NHa CO Molecular Equation [3 points lonic Equation [2 points) Net lonic Equation [1 point) Also using the information in the table above, indicate whether or not a precipitate would be formed from the reactions given below [8 points) Reactants P precipitate NP no precipitate CuSO+2Na PO NiCh + Na CO Na CO + H 5O4 Page 8 of 10
