    media types such as chemical defined‚ complex‚ selective‚ and differential media. Experimental Methods In this lab‚ we use the procedure from Chemically Defined‚ Complex‚ Selective‚ and Differential Media. We divide the agar plates that have the unknown in third‚ write our initials‚ and date on the bottom of the agar plate. We also divide the agar plates into quadrants‚ label each organism in their quadrant‚ write our initials‚ and date on the bottom of the agar plates. We flame the loop and let

    LAB FACILITATOR : REPORT DUE DATE : 4 OCTOBER 2013 INTRODUCTION The laboratory method used in the experiment 1 is titration. The technique of titration finds many applications‚ but is especially useful in the analysis of acidic and basic substances. Titration involves measuring the exact volume of a solution of known concentration that is required to react with a measured volume of a solution of unknown concentration‚ or with a weighed sample of unknown solid. A solution of accurately

    Common Introduction: -Beer-Lambert Law found by Beer August and Johann Heinrich Lambert is the linear relationship between the attenuation of light and concentration of the material through which the light is travelling. It states the absorbance is proportional to the concentration when a parallel beam of monochromatic radiation of equal pathlength is passing through a homogenous concentration. A=εbc‚ where A is absorbance‚ ε is molar absorptivity (L molˉ1cmˉ1)‚ b is the pathlength (1cm) and c

    solution. In titration ‚ permanganate solution is put in the burette and is run down to an acidified solution of reducing agent‚ e.g..ammonium iron(II) sulphate solution.In this experiment‚ KMnO4 will be used to determine the percentage of Fe2+ in an unknown solid sample dissolved in water. The permanganate oxidation of Fe2+ to Fe3+ is carried out in an acidic solution to prevent the air oxidation of Fe2+.A potassium permanganate solution will be standardized by titrating it with a

    A titration is a method where a solution of known concentration is used to determine the concentration of an unknown solution. Typically‚ the known solution is added from a burette to a known amount of the unknown solution until the reaction is complete. Knowing the volume of the known solution added allows the determination of the concentration of the unknown. Often‚ an indicator is used to usually signal the end of the reaction‚ the endpoint. Concentration is the abundance of a constituent divided

    Acid Base Titration Purpose: The purpose is to calculate the molarity of a NaOH solution by titrating the base with 5mL of standard HCl solution in each trial. By adding the base with unknown molarity to the acid with 0.10M the molarity of NaOH can be calculated. The base‚ NaOH‚ helps bring the pH of the acid‚ HCl‚ closer to seven‚ which neutralizes it. When using the buret the amount of NaOH used is able to be determined. Then by writing a balanced chemical equation and using the titration
