Hydrogen peroxide - acid
Isopropyl alcohol - base
Tonic water - base
Vinegar - acid
Pepto-Bismol - base
Saline solution - base

I'm to list two acids and two bases using that list there. The thing is, my parents couldn't get all of the equipment I needed for the assignment those options are coming from so I'm left to guess. Could someone tell me what I got wrong?

if something has a pH of  7 is it an acid or is it a base

[mrdeadman]

i think tonic water is an acid because of the CO₂ that comes out forms acid, just like soda. also im pretty sure alcohol is neither.

If anything, isopropyl alcohol would be acidic, however, for most purposes it is considered neutral.
mrdeadman's right about tonic water being acidic.
A solution of NaCl is neutral.

To all those who answered

We have votes for acids and neutrals
But there is supposed to be 2 bases
Who wants to vote on the bases?

If your saline solution contains a buffer, it might be slightly basic, but the other items on the list are NOT bases.

Tonic water is quite acidic (pH about 3)
Vinegar is defintiely acidic (pH typically around 3)
Pepto-Bismol is weakly acidic (pH about 6)
Hydrogen peroxide in water is also acidic (35% peroxide solution has a pH of 3.5).
Isopropyl alcohol, like will said, is very weakly acidic but its pH is so close to 7 that it's considered neutral.
