Well I got to do a science practical on chemical systems.On fertilisers, petrol(SASOL), soap and detergent industry or galvanic cells.egTake two types of fertilisers with different chemical ratios and use them on same plant and see for resultsThats and easy 1 and I cant use that oneYou can also include the way they are manufactured for example sasol uses fractional distillation.etc.I have tons of information on that I just don't know how to in co operate everything nicely.It should also be a practical that can easily be done at home Please help me with ideas.Oh and I'm in gr12Thnx!
Try textile dyeingYou would have to use pure materials in your practical partFor example, go to a fabric or sewing store and buy a yard each of cotton, polyester, silk, and woolSpecify no blendsFor the dyes, you can get turmeric and saffron in the spice rack of a supermarketDon't get commercial dyes whose ingredients are secretSaffron is expensive, but maybe your parents will spring for itTo test the effect of a mordant, get Burrows solution from a drug storeThis is a package of two packets that make aluminum acetate solution when mixed fresh in water3Ca(C2H3O2)2(s) + Al2(SO4)3(s) H2O 3CaSO4(s) + 2Al(C2H3O2)(aq)Always mix the solution fresh before dyeingYou can cut the fabrics into squares and staple labels to each written with India inkDye some with turmeric and some with saffronDye some by soaking in Burrows solution first and some notLet them all dryWash and dry each 10 times or soCompare the fastness, which is the retention of color with washingMount the fabric squares on poster board with labelsYou can look up the chemical composition of fabrics, the chemical composition of dyes, the dyeing process, mordants, and fastnessYou'll be so erudite that people won't be able to stand you.
