PH Indicator in Faridabad

We know that pH Meter shows H+ ion Concentration in term of pH Value. Two screws are provided at front panel to calibrate at 4.00 pH and 7.00 pH Value; PH Indicator in Faridabad

While the H+ ion concentration is more than 7.0 pH, the solution is acidic; when the H+ ion is less than 7.0 pH, then the solution is alkaline. Low pH indicates high H+ ion concentration; High pH indicates low H+ concentration. Hence the pH scale is inversely related to the concentration of H+ in any given solution, and directly related to OH– ion concentration.

pH Value Scale for pH meter; PH Indicator in Faridabad

While we test many experiments, Hence it is important to check the pH of any given chemical solution. while the pH is checked by pH or litmus paper. The change in litmus paper color indicates the change in pH, it is called as a visual method. For precise noting of pH, an instrument is used and it is called a pH meter. The pH meter works on the potentiometric principle. PH Indicator in Faridabad

Working Principle of pH meter: PH Indicator in Faridabad
The working of pH meter is based on Nernst equation. Nernst equation derives the relation between the electric voltage with ion concentration. The Nernst equation derived for H+ ion concentration is the basis of pH meter. The working principle of pH meter is the potentiometry. The pH meter consists of glass (also called as indicator electrode) and reference electrode. The glass electrode consists of glass membrane, which is sensitive to hydrogen ion concentration of test sample solution. And the glass electrode potential varies from sample to sample. The reference electrode is standard and has constant potential. The reference electrode does not respond to test sample solution. The pH meter measures and compares the potential difference between both glass and reference electrodes.


Construction of pH meter:

While we discuss about Construction of pH Meter, Hence it is clear that, The pH sensor or probe of modern pH meter is a combined type, in which test and reference electrode are placed into a Glass tube like structure. The combined electrode consist of following parts-

design and Construction of pH meter Probe PH Indicator in Faridabad

1. Glass bulb: It is a sensor that senses the H+ ion concentration and it is made from special type of glass and membrane. The glass bulb consists of 0.1M HCL Solution.
2. Internal electrode: this electrode made by silver chloride.
3. Internal solution: The silver chloride electrode is dipped in buffer solution of 0.1 mol/L KCL of pH 4 to pH 7.
4. Reference Electrode: It is also the silver chloride electrode use for reference.
