Solution for Cleaning, Adjusting and Calibrating Probes tendance

Description

Standard solutions are solutions that resist changes in pH when small amounts of acid or base are added to it. Acidic standard solutions are simply those with a pH of less than 7. They are usually made from a weak acid and one of its corresponding salts.

Alkaline standard solutions: An alkaline standard solution has a pH greater than 7. They are made from a weak base and one of its corresponding salts.
