1. If the membrane potential of sodium ions in a cell is equal to +60 mV, what is its membrane potential for chloride ions if they are found in the exact same concentrations as sodium? Give your answer in mV. 2. Given a cell membrane with the following parameters- Ion Extracellular concentration (mmol/L) Intracellular concentration (mmol/L) Permeability K+ 10 150 1 Na+ 140 15 0.04 Cl- 100 7 0.45 calculate the membrane potential of the cell in mV. (Round your...
A sodium ion electrode was calibrated by measuring the cell potentials of several standard Na+ solutions. The other electrode was the SCE. The calibration data are shown in the following table. Log[Na+] Ecell (mV) -1 -165.6 0 -110.0 1 -51.8 2 6.5 3 64.5 a. Plot a calibration curve for these data. b. Determine the slope and intercept for the regression line of this plot. Is the response of this sodium electrode Nernstian? Explain. c. A 10.00mL aliquot of table...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
