 * fierst day || [[image:IMAG0084.jpg width="80"]] First, we mixid copper and nitric acid in the baeker.

Cu+HNO3 -> Cu(NO3) + H2O || This compound made the red and dangerous gas. ||
 * || [[image:IMAG0104.jpg width="80"]]Copper nitrate changed color to blue and add the heat from under the beaker. ||
 * day2 || [[image:IMAG0105.jpg width="80"]]We add Sodium Hydroxide and keep add the heat then, this copper nitrate change color to black.

Cu(OH)2 -> CuO + H2O || put out water for CuO+H2O || CuO+HCl->CaCl || it is CaCl color is change to green blue. || the litmus paper into the CaCl and add NaOH || add more NaOH to CaCl ||
 * day3 || [[image:IMAG0116.jpg width="240" height="142"]]
 * day4 || [[image:IMG_20130502_130747.jpg width="160" height="119"]]add HCl to CuO+H2O.

 * day5 || [[image:IMAG0129.jpg width="160" height="95"]]
 * day 6 || [[image:IMAG0131.jpg width="160" height="95"]]
 * day7 || [[image:IMAG0140.jpg width="160" height="95"]]CaCL is go duon to under the cup. ||
 * || [[image:IMAG0142.jpg width="160" height="95"]]pH is 9 caler is look like green. ||
 * || [[image:IMAG0145.jpg width="160" height="95"]]change water to wash CaCL. ||
 * day 8 || [[image:IMAG0156.jpg width="80" height="130"]] add heat and mixed water and CaCl ||
 * || [[image:IMAG0158.jpg width="160" height="94"]]add HCl to CuO. changed CuCl2, and changed calor from dark blue to clearly light green. ||
 * || [[image:IMAG0160.jpg width="160" height="95"]]add NH3PO4 to CaCl2. changed Cu3(PO4)2, and changed color from clearly light green to get muddy blue. ||
 * || [[image:IMAG0163.jpg width="160" height="95"]] filtered this Cu3(PO4)2. ||
 * Day9 || [[image:IMAG0170.jpg width="160" height="95"]]wash Cu3(PO4)2 again and gat water ||
 * || [[image:IMAG0171.jpg width="160" height="95"]]put little AgNO3 to water the water is go white ||
 * Day10 || [[image:IMAG0182.jpg width="160" height="95"]]filter Cu3(PO4)2 again ||
 * || [[image:IMAG0183.jpg width="160" height="95"]] add heat to salt and look this salt use Microscope ||
