When measuring with a pH electrode, several things limit the accuracy of the measurement. In each of the following situations, describe what would cause the observed effect:

A. Acid error occurs when the pH is too low. Example, you have a 0.5 M solution of HCl, but your probe provides a measured pH of 0.50

B. Sodium error occurs when the pH is too high. Example, you have a 0.5 M solution of NaOH, but measure a pH of 13.00

C. You are trying to measure the pH of a biochemical system at --in situ temperatures (37.5 C). Before your experiment, you calibrate the instrument using stock room temperature buffers you pulled from the cabinet. However, your measurements are consistently 0.25 pH units greater than predicted by literature.

(a) In a dropping mercury electrode (dme), a new measurement is made on each drop. The drop size can be controlled by the diameter of the capillary which feeds the dme. Discuss advantages and disadvantages of using a small drop vs. a large drop. (b) Discuss the differences between the hydrodynamic boundary layer and the diffusion boundary layer near the surface of a rotating disk electrode. (c) Discuss advantages and disadvantages of linear vs. cyclic voltammetry.

Match each method validation term to its definition. Precision Detection limit Range Specificity Quantitation Limit Accuracy Robustness Linearity The smallest quantity of analyte that can be distinguished from the blank. A measure of how well plotted data follows a straight line, indicating the response is proportional to the amount of analyte in the sample. Concentration interval over which linearity, accuracy, and precision meet specifications. A measure of how well replicate measurements agree with each other. The ability of a method...

When the antibiotic valinomycin is added to actively respiring mitochondria, several things happen; the yield of ATP decreases, the rate of O2 consumption increases, heat is released, and the pH gradient across the inner mitochondrial membrane increases. Does valinomycin act as an uncoupler or an inhibitor of oxidative phosphorylation? Explain

When the antibiotic nigericin is added to actively respiring mitochondria, several things happen: the yield of ATP decreases, the rate of oxygen consumption increases, heat is released, and the pH gradient across the inner membrane is lost. Explain all four of these experimental observations in terms of nigericin’s mode of action. In other words specifically explain what nigericin is doing and why each of these side effects are occurring. What is common word for nigericin?
