What would happen if iron filings were added to a solution of zinc sulfate?
2. Copper(I) sulfate forms a bright blue solution in water. If a piece of zinc metal is placed in a beaker of aqueous CuSO4 solution, the blue color fades with time, the zinc strip begins to erode, and a black solid forms around the zinc strip. What is happening? Write half-reactions to show the chemical changes that are occurring. What will happen if a piece of copper metal is placed in a colorless aqueous solution of ZnCl2?
What would happen if small amounts of 1M Ba(OH)2 were added to a solution of 1M NH3? The base lonization constant for NHą will go up. The base ionization constant for NHz will go down. The percent ionization for NHz will remain unchanged The percent ionization of NH3 will go up. The percent ionization of NH3 will go down. Submit Answer Tries 0/98
