Acids and Bases Conjugate

What is being donated/accepted between conjugate acid-base pairs?

• a hydrogen (H+) ion

• a hydroxide (OH-) ion

• water

• a neutron

Which of the following shows the correct conjugate acid base pair?

• HCI (acid) / H₃O⁺ (conjugate base)

• HCI (acid) / CI^- (conjugate base)

• HCI (base) / CI^- (conjugate acid)

• HCI (base) / H₃O⁺ (conjugate 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^-

Which of the following are properties of acids but not bases? Select all that apply.

• Changes the color of an indicator

• Sour taste

• Reacts with metals to produce hydrogen gas

• Feels slippery

A bronsted lowry acid

• produces hydroxide ions in a solution

• is a proton donor

• produces hydrogen ions in a solution

• is a proton acceptor

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 arrhenius acid

Acid-base conjugate pairs differ by a single

• Electron

• Proton

• Neutron

• Oxygen

Could C₂H₃O₂^- act as a base when placed in water?

• Yes, because it can accept a H⁺

• Yes, because it can donate a H⁺

• No, because it cannot donate a H⁺

• No, because it cannot accept a H⁺

• a substance that accepts a hydroxide (OH-) ion

If a solution is basic which ion will be more present?

• H+
