is used to distinguish strong acids from weak acids. strong acids have exceptionally high ka values. the ka value is found by looking at the equilibrium constant for the dissociation of the acid. the higher the ka, the more the acid dissociates. q5 how do you calculate the ka of water?

The Ka value is the dissociation constant of acids. It gives information on how strong the acid is by measuring the extent it dissociates. The higher the Ka value, the stronger the acid. What is Ka in chemistry? Ka is the dissociation constant for acids. It is equal to the molar concen...
You can also guess acid strength by looking at the anions of the acids.The more stable the cooresponding anion, the stronger the acid. Logged sdekivit Chemist Full Member Posts: 403 Mole Snacks: +32/-3 Gender: B.Sc Biomedical Sciences, Utrecht University Re:Ka Values and Acid Strength...
Every acid has a characteristic dissociation constant (Ka), which is a measure of its ability to donate hydrogen ions in solution. In other words, Kaprovides a way to gauge the strength of an acid. Larger values signify stronger acids. The pH (power of hydrogen) of a solution is a measu...
