Creative Cartoon Modeling of Chemical Reactions Involving Copper and Sulfuric Acid

This resource focuses on modeling chemical reactions through engaging cartoons, specifically the synthesis of copper sulfate from various copper compounds and sulfuric acid. Students are encouraged to create cartoon characters representing the different atoms involved, such as copper, hydrogen, sulfur, and oxygen, to illustrate reactions like copper with sulfuric acid yielding copper sulfate and hydrogen. The guide also provides key reactions involving metal oxides, hydroxides, carbonates, acids, and neutralization, emphasizing the visual and creative aspects of learning chemistry.

  1. Modelling Reactions D. Crowley, 2007

  2. Modelling Reactions • To be able to model chemical reactions

  3. Quick-fire Metal + oxygen → metal oxide Metal + water → metal hydroxide + hydrogen Metal carbonate + acid → salt + water + carbon dioxide Metal + acid → salt + hydrogen Acid + alkali → salt + water Metal + oxygen → _____ _____ metal + water → _____ _________ + ________ metal carbonate + acid → ____ + _____ + ______ _______ metal + acid → ____ + _____ acid + alkali → ____ + _____

  4. Making salt • Remember, a salt is made during a neutralisation reaction, when an acid neutralises a base • The salt is named as follows: the first part refers to metal (alkali) and the second refers to the acid that was neutralised hydrochloric acid + sodium hydroxide  sodiumchloride + water acid + alkali  salt + water

  5. Assessment • You need to design a cartoon of the reactions which produce copper sulphate • You can use any reaction you want in producing the copper sulphate, but the chemicals you use must be represented by the cartoon character - each type of atom has its own character • E.g. the cartoon character which represents copper may be: and sulphuric acid may be: Sulphuric acid - made up of hydrogen (Bart); sulphur (Marge) and oxygen(Maggie) atoms Copper - just one type of atom

  6. Useful symbols Cu (copper) CuSO4 (copper sulphate) Cu(OH)2 (copper hydroxide) CuCO3 (copper carbonate) CuO (copper oxide) H2SO4 (sulphuric acid) H2 (hydrogen) H2O (water) Example copper + sulphuric acid  copper sulphate + hydrogen Copper (Cu) Sulphuric acid (H2SO4) Copper sulphate (CuSO4) Hydrogen (H2) Although this is not strictly true, as I haven’t represented the correct number of atoms (Simpsons) - i.e. sulphuric acid would really have 2x Bart (2 x hydrogen); 1x Marge (1 x sulphur); and 4x Maggie (4 x oxygen)

  7. Useful symbols Cu (copper) CuSO4 (copper sulphate) Cu(OH)2 (copper hydroxide) CuCO3 (copper carbonate) CuO (copper oxide) H2SO4 (sulphuric acid) H2 (hydrogen) H2O (water) Copper sulphate Copper + sulphuric acid  copper sulphate + hydrogen Copper hydroxide + sulphuric acid  copper sulphate + water Copper carbonate + sulphuric acid  copper sulphate + water + carbon dioxide Copper oxide + sulphuric acid  copper sulphate + water Copper (Cu) Sulphuric acid (H2SO4) Copper sulphate (CuSO4) Hydrogen (H2)
