According to brunsardory definition, an acid is a proton that's h plus donor, while a base is a proton acceptor.
00:10
In this problem, we want to know what a polyatomic h2s04 turns into after it loses two protons.
00:19
So h2s04 is suveric acid.
00:22
So when it loses protons, it does it in two steps.
00:26
The first one is when it lose the first proton, so h plus.
00:29
It turns into h .s .04 minus.
00:35
So when you have the proton released by the molecule, its number of h decreases.
00:42
So that's why from h2 -s -o -4, you see now h -so -4.
00:45
And also, the overall charge of the molecule decreases...
