The equilibrium concentrations must satisfy the following equation: The zinc powder was black in colour while copper (II) sulphate solution was blue in colour because of the presence of copper (II) ions. The mixture was covered with a watch glass and was kept at the water bath at 80oC for an additional 45 minutes. trans-fac isomer [1] .However if forced, the trans-mer isomer can be formed in greater yields For example, with it was tested against Ammonium Chloride, the color of the solution changed to a light green, very identically to Iron (III) nitrate and Ammonium Chloride. stream A mass of 1 g of CoCl 2 .6H 2 O was dissolved in 6 ml of dH 2 O in a 100ml beaker. These isomeric configurations are that of trans-fac, the trans-mer and thecisisomers. {&g{vOvOi??vO^~x77\>nysCn#x:f1w_w8ojM~Rc@8/D')%1CwEw$8Ce\!}eQ4+~|(E?|/__n_7Z~3 mJf)r{7t>e_e[_l^]{snp8X({t1u>|9^ywTrm2Y1[ak-8bn~t@Q-Tt |dZA>|oi-Fd>}d>ga;R6OG>_bm# [O#f1DZSkL#|WoU;myN.HWH{)C|a{(kbu`89>52 ^;\9;;`V1{r,}P"eX&*ZFQcD+21Z3T.FymZSj%gYK+l1!F)q^_ +*#`g34~qd]bCKik;h_t/[W?
