beakers‚ 5 Test tubes 2 250ml Graduated cylinder. The first step is to calibrate the colorimeter with0.20 M Fe(NO3)3and set the absorbance at 470 nm since it is known to keep an acidic solution throughout the entirety of the experiment. It was important to do this right at the beginning of the lab since the zeroed value of the acid was the calibration number for all of the other solutions. A total of seven solutions with different dilutions were used throughout the lab to conduct the equilibrium

Molar Mass Lab 3.09 Molar Mass of Compounds Purpose: The purpose of this experiment is to determine the formula of a copper sulfate hydrate by heating it up. Materials: Hydrate‚ crucible‚ balance‚ Bunsen burner and scale Procedure: First you measure the mass of the empty crucible and record that mass. Then you should fill the crucible with 3-5 scoops of the hydrate and record that mass as well. Heat the hydrate filled crucible above the Bunsen burner for 10 minutes for all f the water to evaporate

nutrients when replenishing glycogen store? The project that I am conducting is concerning the impact of the consumption of chocolate milk and its effects on protein turnover‚ muscle glycogen and performance during recovery from endurance exercise (2). The research regarding this material is relevant because it can possibly affect the way individuals replenish their glycogen stores following exercise to further improve their performance and over all fitness.

Ba(OH)2 of an unknown concentration. In order to obtain the quantitative analysis‚ the exact amount of a particular compound or element present in sample‚ two procedures were performed. The first procedure was by conductimetric titration and by gravimetric determination. The conductivity was analyzed during the reaction between the sulfuric acid (H2SO4) and barium hydroxide (Ba(OH)2). Through the conductivity‚ the equivalence point can be determined; from there‚ the concentration of the Ba(OH)2 solution
