Acid and Base Conjugate

Acid-base conjugate pairs differ by a single

• Electron

• Proton

• Neutron

• Oxygen

According to Bronsted-Lowry, what is the definition of an BASE?

• a substance that donates a hydrogen (H+) ion

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

• a substance that accepts a hydrogen (H+) ion

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

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

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⁺

Which is a characteristic of a base?

• tastes sour

• found mostly in foods

• feels slippery

• turn litmus paper red
