Chemistry

Introduction
This experiment was to illustrate the different fictitious characters of answers. The first type of reaction was a precipitation reaction. This usually occurs between ionic capacitys, al unitary sometimes one of the positive ions was H+, so that one of the reactants and products was an acid. AB(aq) + CD(aq) ?AD(s) + CB(aq) . The second type of reaction was an acidbase reaction. A typical form would be HB(aq) + CD(aq) ?HD(aq) + CB(aq). The third and final type was the redox reaction, which was short for reductionoxidation. In these reactions, electrons were transferred from one substance to another, causing oxidation states to change. We carried out this different types of reactions Pb(NO3)2 (aq) + 2HCl (g) ?PbCl2(s) + 2HNO3 (aq), BaCl2 (aq) + (NH4)2CO3 (aq) ?BaCO3 (aq) + MH4Cl (aq) and BaCl2 (aq) + K2CrO4 (aq) ?BaCO4 (aq) + K2Cl (aq)

Experiment
Place somewhat a squirt (1 mL) of lead nitrate solution, Pb(NO3)2(aq), in a test pipe. Add a few drops of 6 M HCl. As soon as we did it turned white and body of water formed today as if it has a solid in it . Place about a squirt (1 mL) of atomic number 56 chloride solution, BaCl2(aq), in a test underpass. Add five (5) drops of ammonium change solution, (NH4)2CO3(aq) and it turned white.



Place about a squirt (1 mL) of barium chloride solution, BaCl2(aq), in another test tube. Add two (2) drops of kilobyte chromate solution, K2CrO4 and turned yellow immediately. Place a pea-sized amount of sodium carbonate solid, Na2CO3(s), in a test tube and take five drops of the 6 M HCl. Started fizzing immediately. Place 2 mL of 6 M, hydrochloric acid, HCl, in a test tube and add a small amount of zinc. It began fizzing immediately color remained clear continued fizzing. We add copper alternatively of zinc but nothing happened. Add 1 mL of concentrated nitric acid, HNO3, to the copper in the test tube but nothing happened and then added 5 mL of distilled water but there was not change. Place 1 mL (one squirt) of sodium oxalate solution in a test tube. Add...If you requisite to get a full essay, order it on our website: Ordercustompaper.com
