pHmõõtmise
pHmõõtmine refers to the process of determining the acidity or alkalinity of an aqueous solution. It is a fundamental measurement in chemistry and has wide-ranging applications in various fields. The pH scale ranges from 0 to 14, with a pH of 7 considered neutral. Solutions with a pH below 7 are acidic, while those with a pH above 7 are alkaline or basic.
The most common method for pHmõõtmine involves using a pH meter. This electronic instrument consists of a
Another method is using pH indicator strips or solutions. These substances change color at specific pH values.
pHmõõtmine is essential in many disciplines. In environmental science, it is used to monitor water quality
