how come Ag + is an acid but F- is a base????????

[Adam Enomoto 1L]

Ag+ is a lewis acid and F- is a lewis base. Ag+ can accept an electron and F- can donate an electron

[Troy Tavangar 1I]

Acids have the ability to take on an extra electron while bases have the ability to give an extra, therefore Ag+ would be the acid cause it requires an electron to have a neutral charge and F- is a base because it needs to get rid of an electron to have a neutral charge.

[Alexandria Weinberger]

Ag+ is the acid because it will take an electron to become neutral, as F- will take a proton to become neutral so it is the base.

For this question, it was asking about lewis acids and lewis bases. Lewis acids accept electrons and lewis bases donate electrons. Ag+ can accept electrons which makes it an acid, while F- can donate an electron which makes it a base.
