    The sugarcane undergoing fermentation produced a volume of carbon dioxide that was nearly nine times more than the corn‚ wheat grain and wheat stalk. Wheat grain and corn was nearly doubled that of the wheat stalk and the control (Figure 1). Sugarcane was the leading plant material producing the highest volume of carbon dioxide (mean= 19.9 ± 0.996 mL) while other than the control; the wheat stalk produced the lowest volume of carbon dioxide (mean= 1.33 ± 0.036 mL). As time elapsed‚ the sugarcane

    Hydrated Salt Lab Report

    In this lab‚ we used Bunsen burners to heat up a hydrated salt in order to determine the percentage of water inside of this hydrated salt. We heated up the salt in order to boil off the water‚ which allowed us to find the weight of the CuSO4 by itself. By comparing this final weight with the original weight and subtracting the difference‚ we were able to compile data about how much the weight of the hydrated salt decreased as the water gradually boiled away. In doing so‚ we were able to find the

    Unit 2 PPA 1 Complexometric Determination of Nickel using EDTA Introduction: The Aim of the experiment is to determine the percentage of nickel salt using a complexometric technique. Ethylenediaminetetraacetic acid (EDTA) is a hexadentate ligand which forms stable complexes with most metal ions‚ thus is widely used to determine metals in complexometric titrations. EDTA can be represented as H4Y and in alkaline conditions‚ it exists as Y+ ions: The Y4- ions form 1:1 complexes with metal ions

    Lab: Flame Test Purpose: to determine the ID of 2 unknown substances Background Information: Every atom consists of a nucleus with tiny electrons whizzing around it. The further away from the nucleus they are‚ the more energy the electrons have. If a metal atom is heated‚ the electrons get enough energy to jump higher away from the nucleus‚ they become “excited”. When they fall back closer to the nucleus (back to their ground state)‚ they give off this extra energy as light. Why is the
