IMAGE. A glass electrode. In the electrode shown, the glass is set in a plastic holder to protect it.
A pH meter represents the hydrogen ion concentration in pH units. A pH meter consists of a glass electrode and a read out screen. The glass electrode is made of very thin glass that establishes and measures the electrical potential difference between the analyte solution (the solution to be measured) and an internal reference. The electrical potential is then converted into a pH reading for the sample.
What is the relationship between pH and hydrogen ion concentration?
Answer
Hydrogen ion concentration can be calculated from the pH of a solution using the following equation:
