The Nernst equation thus reduces to E E S log c lon selective Analysis Methods Direct Analysis In this method a sample concentration is determined by measuring the electrode potential and comparing to those obtained in standard solutions Normally an ionic strength adjustor and or pH adjustor must be added to both the samples and the standards This helps in that the closer the standard solution matrix is to the sample matrix the more valid is the analysis A number of standard solutions are used to standardize a pH mV ion meter or to construct a calibration curve by plotting the electrode s output in mV versus the log of the concentration The sample concentration is then read from the meter or the calibration curve The advantages of the direct method of analysis are 1 Many samples particularly those with relatively simple ionic backgrounds can be quickly measured after a single calibration procedure 2 The technique is valid over a wide range of concentrations 3 Sample volume values are not required and may also vary over a wide range 172 accumet excel gt Fisher Scientific Accumet XL Series User Manual Authorized Distributor Clarkson Laboratory amp Supply Inc www clarksonlab com E mail sales clarksonlab com Incremental Methods These procedures can reduce errors caused by temperature variations complex matrices and complexation They are also useful for applications where only occasional sa

The dyes can be added directly to the solution or impregnated onto paper which may be dipped into the solution At best these colorimetric methods yield approximate pH values often with an accuracy of plus or minus 0 5 pH units The preferred and most accurate way to measure a pH value is the potentiometric measurement using a pH electrode a reference electrode and a pH meter This method is based on the fact that certain electrodes immersed in solution produce a millivolt potential i e voltage that is related to the hydronium ion concentration or pH of a solution in a precise way The relationship between the electrode s voltage and the solution pH is defined by the Nernst equation 2 3RT Emeas E nF pH In this equation Emeas is the voltage output of the electrodes E is the total of all other voltages in the system including the reference voltage R is the Gas Law constant T is the temperature in Kelvin n is the charge on the hydronium ion 1 and F is the Faraday constant pH Meter The pH meter is a sensitive voltmeter capable of accurately measuring small voltage differences between the pH electrode and the reference electrode This voltage difference is amplified and shown as a PH reading Almost all modern meters are microprocessor controlled and programmed to use electrode voltages efficiency and temperature to calculate an accurate pH for the sample Since the voltage output from different electrodes
