A bronsted lowry acid

• produces hydroxide ions in a solution

• is a proton donor

• produces hydrogen ions in a solution

• is a proton acceptor

Water can act as both an acid and a base according to the bronsted lowry model. This means water is

• neutral

• conjugate

• ionic

• amphoteric

Identify the true statement about the following reaction:

F^- + H₂O --> HF +OH^-

• H₂O is a bronsted lowry base

• H₂O is not an acid or base according to either model

• H₂O is a bronsted lowry acid

• H₂O is an basic acid

Which of the following show an acid and its conjugate base pair (in that order)

• H₂SO₄, SO₄^2-

• OH^-, H₂O

• NH₄⁺, H₂O

• H₂CO₃, HCO₃^-

What is the conjugate acid to OH^- ?

• H₂O

• OH^-
• H⁺
• This does not have a CA.

NH₃ + H₂O --> NH₄⁺ + OH^-

What is NH₄⁺ in this reaction?

• acid

• base

• conjugate acid

• conjugate base
