Question

In the reaction below does water acts as the acid or as the base?

H2S + H20 - HS1- + H30+ *
O a. Neither, water is neutral
O b. Acid
O C. Base

Answer 1

C. Base.

Step-by-step explanation:

Hello there!

In this case, according to the given information, it turns out convenient for us to realize that the concept acid and base we should use here is based off the Bronsted-Lowry one, which says that an acid is a hydrogen donor. In such a way, since water accepts one H ion as it goes to H3O⁺, we infer it is C. Base and the H2S the acid.

Also, we can tell HS⁻ is the conjugate base and H3O⁺ the conjugate acid.
