Problem 18.135

A galvanic cell is constructed by immersing a piece of copper wire in 25.0 mL of a 0.20 M CuSO4 solution and a zinc strip in 25.0 mL of a 0.20 M ZnSO4 solution. (a) Calculate the emf of the cell at 25C and predict what would happen if a small amount of concentrated NH3 solution were added to (i) the CuSO4 solution and (ii) the ZnSO4 solution. Assume that the volume in each compartment remains constant at 25.0 mL. (b) In a separate experiment, 25.0 mL of 3.00 M NH3 are added to the CuSO4 solution. If the emf of the cell is 0.68 V, calculate the formation constant (Kf) of Cu(NH3)4 21

Step-by-Step Solution:
Step 1 of 3

Cell Structure 1. Cell a. Cella (store room or chamber) i. The smallest cell is 2 microns ii. The largest cell is more than a meter (nerve cell) iii. 200 different types of cells with different structures and functions b. Basic living, structural and functional units of all organisms 2. Cell Theory a. Cell is structural and functional unit of life i. In order for something to labeled as living, it has to be made up of cells. b. Activity of organism is combined results of individual and aggregated cells i. Activity of individual is based on the activity of the cells. c. Activity of cells depends on subcellular composition i. Rich in mitochondrion= produces lots of energy ii. Called the Principle of Complementarity d. Cells responsible for continuity of life i. Cells are made up of chemicals 3. Parts of a Cell a. Plasma membrane  Allows a cell to have on thing on one side and something on the other  Can limit the activity of a cell and decides what goes in and out of the cell. i. Composition of Plasma Membrane 1. Phospholipid bilayer a. Protecting the hydrophobic parts b. Makes up about half of border of cell c. 7-
