Conductivity of Ionic and Molecular Aqueous Solutions Abstract Aqueous solutions that have free ions have higher conductivity values than solutions with most molecules. The purpose of the experiment was to see if ionic strength of an aqueous solution determines its conductivity. We tested each compound by putting the conductivity probe into its aqueous solution. Then the computer would analyze the data and give us a conductivity value. After each solution was tested‚ we used deionized water to

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

Chemistry 112: Anion Analysis Page 7 ANION ANALYSIS M uch of the work you will be doing in the Chemistry 112 laboratory will be concerned with identifying positive and negative ions‚ that is‚ cations and anions‚ in solutions whose composition is unknown. This procedure is called QUALITATIVE ANALYSIS. The modern chemist frequently wishes to identify the constituents in a very small amount of substance‚ and so he depends heavily on instrumental methods of analysis. While the procedures
