Chemical reaction-Pipette 0.25 M solution of iron(III) chloride (FeCl3) into 0.5 M solution of sodium carbonate (Na2CO3). Rusty red iron(III) hydroxide precipitate (Fe(OH)3) & carbon dioxide produced

Chemical reaction-Rusty red iron(III) hydroxide precipitate (Fe(OH)3) in test tube formed reaction between iron(III) chloride (FeCl3) & sodium carbonate (Na2CO3): FeCl3+Na2CO3+H2O ->Fe(OH)3+NaCl+CO2

Chemical reaction-Pipette 0.5M solution of copper sulfate (CuSO4) into 0.5M solution of sodium carbonate (Na2CO3). Blue copper carbonate precipitate (CuCO3) formed result: CuSO4+Na2CO3->CuCO3+Na2SO4

Chemical reaction-Pipette 0.5M solution of sodium carbonate(Na2CO3) in 0.25M solution of lead(II) nitrate (Pb(NO3)2). White lead(II) carbonate precipitate(PbCO3) result: Pb(NO3)2+Na2CO3->PbCO3+NaNO3
