The calibration curve and the calibration equation above was obtained by plotting absorbance Vs. [KMnO_4]. In the calibration equation y = 4.84E+03 x - 2.26E-01, what does y and x represent, respectively? If the absorbance of a KMnO_4 solution of unknown concentration is 0.833, calculate the concentration of KMnO_4 in the solution. Show your calculation.

Calibration data for a bromide ion‑selective electrode (ISE) was collected and recorded in the table. The potential of the ISE was measured against a saturated calomel electrode (SCE). All solutions were buffered at a pH of 7.56. A linear calibration curve can be constructed from this data as a plot of potential (in mV) vs. pBr. Determine the slope and y‑intercept of such a plot of the calibration data given. Br-M Potential (mV 0.300 -21.6 0.0300 36.7 0.00300 96.5 0.000300...

You begin preparation of the calibration curve to measure absorbance vs concentration of FeSCN2+. To do so, you add 4.614 mL of 0.200 M Fe(NO3)3 to a cuvette and then directly add 108 µL of 0.001 M KSCN. What is the resulting concentration of FeSCN2+, assuming complete conversion of SCN- to FeSCN2+? Enter your answer in units of mM to four digits after the decimal.
