10/16 Intro to acid/base equilibria

What characteristic(s) best describe a strong acid/base?

• Fully dissociates

• Tends to produce more products

• It's more reactive

• Equilibrium problem

Strong acids have [blank] conjugate bases compared to weak acids.

If we have a weak base, we can expect to have a strong conjugate [blank].

Which option best describes an Arrhenius base?

• Gains/accepts H⁺

• Accepts an electron pair

• Increase in the concentration of OH^- when dissolved in H₂O

• Decrease in the concentration of OH^- when dissolved in H₂O

When we identify acid-base conjugate pairs, we are using this classification concept.

• Arrhenius

• Bronsted-Lowry

• Lewis

• None

Identify the acid-conjugate base pair from the following reaction.

• Not possible to identify
• NH₃/NH₄⁺

• HBr/Br^-

• HBr/NH₄⁺

Identify the acid-conjugate base pair from the following reaction for the REVERSE reaction.

• Not possible to identify
• NH₄⁺/NH₃

• HBr/Br^-

• Br^-/HBr

Identify the base-conjugate acid pair from the following reaction.

[Be sure to put your answer as: base/conj.acid]

When pH increases, the concentration of H⁺ [blank].

You are told that a solution has a OH^- concentration of 10^-3. What is the pH of this solution?
