We mixed 3 ml of 1M copper solfate solution and 3ml of sodium chloride solution. This main copper ions are presented as Cu(h20)6 2+ We heated the test tube to produce cucl42- ions. This is part a) We placed 1M of copper2 sulfate solution in anoter test about 2 cm depth and slowly added 1 M sodium hydroxide solution and a thick precipitate formed. We added 2M ammonia solution to this mixture and cy(Nh3)4 2+ ions are formed. This is part b) Is it possible to use stoichiometry to calculate the respective concentration, num of moles of them all Ie Initaially Reaction Equilibrium.
