Match the acid and base to it's definition

Below is a Bronsted acid-base reaction.

HF is a Bronsted Lowry acid which means it is a proton donor.

PO4-3 is a Bronsted Lowry base which means it is a proton acceptor.

The reactants are given to you. What do you predict that the products will be? Remember: a proton is also known as H+

Look at the equation below.

On the equation below, fill in the blank on the red lines on which reactant you think is the bronsted lowry acid and which reactant you think is the bronsted lowry base.

What is the conjugate acid of H2O?

What is the conjugate base of H2O?

Why can water be considered a conjugate acid or conjugate base?

For the Equation:

HClO4(aq) + H2O(l) ⇄ H3O+(aq) + ClO4–(aq)

What is the Acid?

For the equation

H2SO3(aq) + H2O(l) ⇄ H3O+(aq) + HSO3–(aq)

What is the base?

For the equation

HC2H3O2(aq) + H2O(l) ⇄ H3O+(aq) + C2H3O2–(aq)

What is the Acid conjugate base pair?

For the equation

H2S(g) + H2O(l) ⇄ H3O+(aq) + HS–(aq)
