What is a pH electrode?
A glass electrode is a type of ion-selective electrode made of a doped glass membrane that is sensitive to a specific ion. The most common application of ion-selective glass electrodes is for the measurement of pH. The pH electrode is an example of a glass electrode that is sensitive to hydrogen ions.
How does a pH electrode work?
Acidic solution has more Hydrogen ion concentration than alkaline solution. pH probes measure pH by measuring the voltage or potential difference of the solution in which it is dipped. … So, to make electricity flow through the test solution, you have to put two electrodes (electrical terminals) into it.
What is the principle of pH?
A pH meter provides a value as to how acidic or alkaline a liquid is. The basic principle of the pH meter is to measure the concentration of hydrogen ions. Acids dissolve in water forming positively charged hydrogen ions (H+). The greater this concentration of hydrogen ions, the stronger the acid is.
What is pH theory?
pH is defined as the negative logarithm (base 10) of hydrogen ion concentration. If the hydrogen ion concentration is very high, the pH value is very low. This is determined using a scale ranging from 0-14 called the pH scale. It was introduced by a Danish chemist Soren Peder Lauritz Sorensen.
How do you measure pH in water?
The outcome of a pH-measurement is determined by a consideration between the number of H+ ions and the number of hydroxide (OH-) ions. When the number of H+ ions equals the number of OH- ions, the water is neutral. It will than have a pH of about 7. The pH of water can vary between 0 and 14.
