  • Calcium nitrate, or calcium nitrate
  • Tubes
Instruction
1
Does copper sulphate (you can buy at the hardware store) and mixed in a test tube with ammonia (sold at the pharmacy, can be taken from the home kit) to the slightly bluish hue while falls a precipitate of the hydroxide of copper.

CuSO4+2NH4OH => Cu(OH)2+(NH4)2SO4
The formulas are given in a simplified form, for ease of perception and adjustment.
2
The next moment is the direct production of ammonium nitrate. The resulting ammonium sulfate ((NH4)2SO4) is mixed with the calcium nitrate (which is also sold in hardware stores), we obtain a precipitate of calcium sulfate. Next, drain the solution out of the vial, which contains ammonium nitrate.

(NH4)2SO4+Ca(NO3)2 => 2NH4NO3+CaSO4
