For this lab, seven small experiments were performed. First, solid Mg was combined with a HCl solution. The reactants started to bubble and give off a colorless gas was given all while the Mg was dissolving. Next a Pb(NO3)2 solution was mixed with a KI solution. These two clear, colorless liquids produced a transparent yellow liquid and yellow sediment at the bottom of the test tube. After that, CuSO4 ∙ H2O, a fine blue crystal solid, was heated to leave behind a white powdery solid. Next a HCl solution and NaOH solution with phenolphthalein were combined. When the HCl solution was added to the NaOH, its color changed from purple to clear. Following that experiment, Cu was heated in the presence of O2. The shiny, copper colored metal turned dark gray and lost its luster. After that, a CuSO4 solution was combined with solid Fe to produce rust. Lastly, a FeCl3 solution (yellow in color) was mixed with a NaOH solution (colorless in color) to yield a cloudy orange liquid.
Abstract Sugars catabolize through the process of glycolysis. Glycolysis causes the sugar to undergo phosphorylation and ferment, which yields CO2. In this experiment, different sugar solutions were mixed with a yeast solution. The yeast solution caused the sugar solutions to undergo glycolysis and produce . . .
