A Chemical Change
Introduction:
There are large varieties of experiments that can study and demonstrate chemical change. Following is a list of different types of chemical changes with description and possible experiments to demonstrate that.
 Type Definition Examples
 synthesis a compound forms from simpler reactants C2H4(g) + H2O(g) =>C2H5OH(g)
H2(g) + ½ O2(g) =>H2O(l)
 decomposition a compound breaks down into simpler products CaCO3(s)=>CaO(s) + CO2(g)
2NH4NO3(s)=>2N2(g) + 4H2O(g) + O2(g)
2 H2O(l) =>2 H2(g) + O2(g)
 displacement   Zn(s) + 2 HCl(aq)=>ZnCl2(aq) + H2(g)
Zn(s) + CuCl2(aq)=>ZnCl2(aq) + Cu(s)
 neutralization H+ transfer from acid to base NaOH(aq) + HCl(aq)=> H2O(l) + NaCl(aq)
KOH + HC2H3O2(aq) =>H2O(l) + KC2H3O2(aq)
 precipitation a solid product from aqueous reactants BaCl2(aq) + Na2SO4(aq) => BaSO4(s) + 2 NaCl(aq)
AgNO3(aq) + NaCl(aq) => AgCl(s) + NaNO3(aq)
 redox electron transfer between reactants 2 C2H6(g) + 7 O2(g)=> 4 CO2(g) + 6 H2O(g)
 
 Material and instructions:
There is a wide range of experiments related to chemical change. Some are so simple and are good for lower grade students while some others are complicated and require additional skills and equipment. Some chemicals, basic lab equipment and adult supervision are required to conduct some of the above experiments.
