In this experiment‚ you will analyze a known solution that contains the entire Group I cations—silver‚ lead‚ and mercury (I)—and an unknown solution to determine which ions are present and which are absent. II. DISCUSSION: The chlorides of Pb2+‚ Hg22+ and Ag+ are all insoluble in cold water. They can be removed as a group from solution by the addition of HCl. The reactions that occur are simple precipitations and can be represented by

new invention has discovered a method to stabilise an enzyme during freezing providing the enzyme in a zwitteronic buffer solution. A zwitterionic composition is useful as a surface active agent in aqueous solutions. The buffer solution has the capacity to stabilise an enzyme‚ such as glocuse oxidase‚ in a liquid state whilst providing protection if the the end solution is frozen. The zwitterionic buffer can stabalise the activity of enzymes by preventing large pH shifts during freezing.

the percentage purity of the iron(II) salt in an unknown sample. We performed titrations using Potassium permanganate which is a strong oxidizing agent‚ with unknown sample dissolved in deionized water. The result of the experiment was a 99.5% purity for the anhydrous iron (II) ammonium sulfate. Introduction: In this experiment‚ oxidation/reduction (or redox) will be used in the titration analysis of an iron compound. We will use potassium permanganate‚ KMnO4‚ as the titrant in the analysis

Homework #1 Solutions 3.1 a. Let X1 =the number of hours of process 1 used X2 =the number of hours of process 2 used The objective is to minimize the cost of producing the three products A‚ B and C. The constraints are on the demand of each product. Min 4X1 + X2 subject to 3X1 + X2 ≥ 10 (A’s demand) X1 + X2 ≥ 5 (B’s demand) X1 ≥ 3 (C’s demand) X1 ‚ X2 ≥ 0 (nonnegativity) b. From the graph we can see that the isocost line just leaves the feasible region where the demand for C and B intersect. The
