Question 1

Binary Acids

Answer 1

Acid H+ attached to a nonmental particle (HCl)

Question 2

Oxyacids

Answer 2

H+ attached to an oxygen atom (Sulfuric acid)

Question 3

Carboxylic acid

Answer 3

Answer 4

H₂0
H⁺ + OH^- H₂O

Question 5

According to the Brownsted-Lowry definition, what is an acid and what is a base?

Answer 5

An acid will be a proton donor and a base will be a proton acceptor.

Question 6

Any reaction involving H+ transfer from one molecule to another is an _______________ rxn, regardless of whether it occurs in aqueous solution or if there is OH- present.

Answer 6

Acid-base

Question 7

Weaker

Question 10

A strong acid has a weak _________

Answer 10

Conjugate base

Question 11

How do we classify weak acids?

Answer 11

Answer 13

Inversely proportial

Question 14
