I was searching for a reaction to know which solution contains CuCl and which solution contains CuCl2...
There was a NH3 + CuCl Solution and CuCl2 solution.
When i added H2O2 to CuCl solution , dark-brown percipate was fromed.It was like sensitive to air. When it contacted with air its color turned to dark-yellowish-green.The color of this solution was always blue what with brown percipate the bottom.
When i added H2O2 to CuCl2 solution , a greenish - white colored percipate was formed.But i have no idea about its sensitivity to air.The Solution wast blue . The firs drops of NH3 formed the blue color as i waited at the surface after mixing it color was gone.
What are they could be ??
