I missrwrote F and OH it is : $$F^{-}; OH^{-}$$

matt101 · Answer

A Bronsted-Lowry base is a proton acceptor. In other words, it has the ability to combine with H+.

Which of those you listed are able to do this?

rock_mit182 · Answer

well the only acid that i see is water..

rock_mit182 · Answer

$$SO_{4}^{-2}$$ that ion would be an acid if only there was a H^{+}

rock_mit182 · Answer

well I know for sure that OH^{-1} IS A BASE..

matt101 · Answer

So which of your options are able to gain an H+?

rock_mit182 · Answer

$$F^{-}; OH^{-1}; SO_{4}^{-2}$$

rock_mit182 · Answer

But i heard also water behaves like a base as well behaves as an acid

matt101 · Answer

You're right!

In fact, EVERYTHING you listed can act as a Bronsted-Lowry base. Everything except water is a negative ion, so all these ions are capable of accepting a proton.

However, as you said, water can also act as a Bronstead-Lowry base by accepting a proton to form the hydronium ion, H3O+.

rock_mit182 · Answer

im not sure about O ^-2  i guess would form OH ..

matt101 · Answer

Yes that's right!
