a) When considering the overall dialysis procedure, why is it important to exchange old/used dialysis buffer (or “dialysate” solution) with a fresh dialysis buffer solution at least once throughout the process? NOTE: Your TAs will do this for your group’s samples over the next week. b) This week’s lab utilizes a dialysis buffer with the following composition: 10 mM Tris-HCl, 10 mM MgSO4, and a pH of 7.4. Let’s presume an ERROR occurred with the creation of this buffer during the pH titration and you unknowingly titrated to a final pH of 5.0. What effects, if any, could you expect to observe on your final, dialyzed sample?
For titration, what is the purpose of a dropwise rate?
A suitable target for the titration is 30.0 cm3 of 0.025 moldm-3 Br2(aq) Justify why a much smaller target titre would not be appropriate Calculate the amount in moles of bromine in the target titer Justification? calculate a suitable massof alive oil to transfer to the volumetric flask using your answer to of above question and the structure of Y Assume that the olive oil contains 85/- of Y by mass (If you were unable to calculate the amount of bromine in the target titer,you should assume it is 6.25×10^-8 mol .this in not the correct amount)
‘In the gravimetric analysis a washing liquid should not form volatile or insoluble product with the precipitate’. In the above statement analyze the consequences if washing liquid reacts with the precipitate.
Sources of Error Determine the relationship between the observed/apparent value (EX) VERSUS that of the true value (ET) for the quantity being sought by writing either <, >, or = on the space provided TOPIC: Measured mass of the precipitate Question 4 Overignition which causes the conversion of BaSO4 precipitate to BaO. EX ___ ET Question 5 Precipitate was not washed thoroughly. Ex ___ ET TOPIC: Standardization of Titrant Question 6 Adding insufficient amount of titrant to reach acceptable endpoint color: EX ___ ET
Why homogenously formed precipitates are better suited for analysis than aprecipitate formed by direct addition of a precipitating agent? no copy from google. if copied please paraphrase or summarize
volumetric or graduated piptte, Which one of them is commonly used for Titration and reagent and which one is more accurate, why?
Why do you think the contents of Flask B precipated when you added the concentrated HCl solution. Explain in terms of solubility, being specific with the chemistry in the answer
In this activity, you will develop an experimental procedure to solve a problem. Consider the followingscenario:You are the manager of a chemical stockroom, and find a bottle containing approximately one liter of aclear and colorless solution of unknown identity and concentration. Your only clue to its identity is thatit was found between bottles of silver fluoride and sodium fluoride, so it is likely an aqueous solution ofone of those two compounds. You will need to develop a procedure to determine the following:a) The identity of the unknown solutionb) The concentration of the unknown solutionWrite out a precise procedure, which includes all glassware, reagents, and steps. You will also need towrite the calculations that you would need to determine the concentration of the solution. Assume thatyou have access to any reagent you might need
Which among these is/are properties for the type of precipitate required in gravimetric analysis? Hygroscopic Known composition Reactive with atmospheric constituents Large particles
Briefly explain why the sparingly soluble product mustbe removed by filtration before you back-titrate the excesssilver ion in the Volhard determination of a) chloride ion. b) cyanide ion. c) carbonate ion.
1. Discuss the a) direct method of weighing b) indirect weighing using the analytical balance. 2. Explain how suction filtration is carried out in the laboratory. Give the important points that must be observed in doing the process. 3. Explain why it is important to wash the precipitate. Can distilled water be used to wash all types of precipitates? 4. Discuss how to use a desiccator. When should a desiccant be replaced? PreviousNext
