Water with Acids and Bases

[Tiffany_Cacy_3D]

So i know several elements can act as both an acid and a base such as water but how do you tell when a water should act as an acid or a base. When do you know when it should give up or accept electrons? Also does water affect the likelihood of certain compounds being stronger or weaker acids or bases?

Water is an acid when it reacts with a base and it is a base when it reacts with an acid. I don't think water affects whether the acid or base it reacts with completely dissociates or not.

You will know if water acts as an base or an acid based off of what compound it is reacting with. If it is reacting with a base, it will act as an acid and donate protons; however, if it is reacting with an acid, it will act as a base and accept protons. And I believe the strength of an acid/base doesn't depend on what compounds they are reacting with, it is an individualistic characteristic.

Water is amphoteric so it can act as either an acid or base, therefore it depends on the other compound involved in the reaction with water to determine water's behavior.
