Protonoitumisasteet
Protonoitumisasteet refers to the degree to which a molecule or ion has accepted protons. This concept is central to understanding acid-base chemistry, particularly in aqueous solutions. When a substance is dissolved in water, it can either donate protons (act as an acid) or accept protons (act as a base). The extent to which it accepts protons is its protonoitumisaste.
In the context of polyprotic acids, which have more than one acidic proton, different degrees of protonation
Similarly, bases can undergo varying degrees of protonation. Water itself is amphoteric and can be protonated
