Concentration of Reagents (NH4)2S2O8 KI Na2S2O3 0.25 M 0.22 M 0.19 M Volumes of Solutions S₂082 (mL) Starch soln (mL) KNO3 (mL) EDTA soln (mL) KI (mL) S₂O32- (mL) x 5 9.7 0.9 26.4 0.5 9.9 1.1 Using the above data determine the concentration of I at the moment the reaction begins. HINT: This is a mixing problem. Determine the total number of moles of I and divide this amount by the total volume (in L). Be careful... If you go back and try this exercise again the values will change. Read the question carefully! Answer:

Question: Why are we using this materials in the experiment is there any reason why we using it? Quantification of Total Protein in Serum Experiment; Materials: Fatty acid free beef albuminl solution: 100 g / L Reagent Ⅰ Sodium potassium tartrate 9g / LSodium hydroxide 0.2 mol / L         Potassium iodide 5 g / L Reagent Ⅱ Serum from blood   Copper sulphate solution: 150 g / L   Working solution: 5 ml of reagent copper sulphate solution is prepared by mixing into 1 L of reagent Ⅱ. This reagent is stable for 6 months at 2-8 ° C Procedure: *Three test tubes are taken. These are marked as blank, standard and sample tubes.*Only 5 ml of working solution is put into the blank tube.*0.1 ml reagent I and 5 ml working solution are put into the standard tube.*0.1 ml of serum and 5 ml of working solution are put into the sample tube.*After mixing each tube separately, it is waited for 30 minutes at room temperature and measured at 545 nm in the spectrophotometer.*Color permanence is…

1-7.) Match the following amino acids with the best representative categories; use each answer only once.

tab caps lock You have a 11.5 mg sample of blood that contains various proteins. Hemoglobin is the only protein in the sample containing Fe. Hemoglobin contains 3.83% by mass of a compound called heme (C34H32FeN4O4, MW = 616.49 g/mol). You find that your 11.5 mg blood sample contains 29.7 micrograms of Fe.

The first step in the procedure asks you to prepare five dilutions of the protein standard (BSA) in the range of 0.2 to 1.0 mg/ml. For each concentration, a volume of 1.0 mL should be prepared. Describe how you will prepare these standards using a stock solution of BSA that is 2.0 mg/ml.

In the space provided, draw the structure of valine (val) at each of the following pH values. Valine has a pl of 5.97. a) pH = 4.34 CH3 CH-CH, H2N-C-COOH Valine (Val) b) pH = 5.97 %3D

You're an undercover biological weapons agent who has been given an unknown liquid - you suspect that it is just sugar water (because you drank some by accident - you know you're not supposed to have food or drink in the lab, but you do it all the time, and it tasted sweet - plus you didn't die!) One of the tests you need to run is to see if it contains protein (remember, foreign proteins can cause severe immune responses which can be a powerful biological weapon). You set up 3 test tubes each with 10mL of the following: distilled water, gelatin solution and the unknown. The distilled water is clear, the gelatin solution is clear with a beige tint, and the unknown is clear. You use Biuret's Reagent - a dark blue dye which will turn a liquid sample purple in the presence of protein. 1. When Biuret's Reagen is added to the unknown, predict what color you expect it to become if the unknown is just sugar water: [a] (no change | blue | purple).   2.You included both a positive and negative…
