    Water Testing Lab Conclusion In this lab‚ chemical tests were used to check for the presence of calcium‚ chloride‚ and sulfate ions in water samples. To do this‚ the testers started with five samples: a reference‚ a sample of only the chemical being tested for‚ a control‚ distilled water‚ two home water samples‚ and a school water sample. To test for the ions in the water‚ a chemical that would react with the ion and create a precipitate was added. If the precipitate was not easily visible‚ a

    Melissa Carrithers 9-17-14 Period: 6 Determination of the Empirical Formula of Silver Oxide Purpose: To find the percent composition and empirical formula of silver oxide can then be calculated‚ based on combining the ratios of silver and oxygen in the reaction. Hypothesis: Silver oxide decomposes to silver metal and oxygen when strongly heated. Heating Silver oxide causes the oxygen to be driven off‚ leaving only the silver metal behind. The total mass of the products of a chemical reaction must

    permanganate (KMnO4) and oxalic acid (H2C2O4)‚ three determinations were performed‚ each with different initial concentrations of the reactants. Each initial concentration resulted in a unique reaction rate; these rates were then examined using the method of initial rates to determine the order of the reaction with respect to both KMnO4 and H2C2O4. The rate constant (k)‚ was then calculated‚ and the rate equation for the reaction written1. In part two; determinations were done at varying temperatures while keeping
