Why is it necessary to rinse the pipets with the solution to be used in them before using the pipets? Why is it necessary to rinse out the cuvette with the solution to be used in it before making our measurements? Why must we use the same cuvette for ail measurements? What is the purpose of "zeroing" the spectrophotometer using a "blank" solution (water)? What assumptions are we making in the calculations and analysis for this lab? 6.019 g of...

A) Why is the method used in this determination of bitterness only an approximation to the true quantity of iso-alpha acids in a sample of beer? B) Although this method gives a good correlation between the bitterness of beer and the quantity of iso-alpha acids when fresh hops are used in the brewing process, the correlation is poor when old hops are used. Explain.
