pH Meter (ChemPages Lab)

pH Meter: this is a resource in the collection "ChemPages Laboratory Resources". 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. The ChemPages Laboratory Resources are a set of web pages that include text, images, video, and self check questions. The topics included are those that are commonly encountered in the first-year chemistry laboratory. They have been put together for use as both a pre-laboratory preparation tool and an in-laboratory reference source.
