Corrode Metals
Have a pH less than 7

Question 5

What is the difference between weak vs. strong acids?

Answer 5

Weak acids:Do not ionize completely
Strong Acids: Ionize completely

Question 6

What is a base?

Answer 6

Proton acceptor, accepts hydrogen ions. Produces OH- ion.

Question 7

Properties of bases (2)

Answer 7

React with acid to form salt and water
Are electrolytes

Question 8

What are acids and bases according to Arrhenius?

Answer 8

Acid adds H+ to aqueous solution
Base adds OH- to aqueous solution
Only hydrogen in polar bonds are ionizable

Question 9

What is an acid and base compared to Bronsted-Lowry?

Answer 9

Acid donated a proton to another substance
Base accepts a proton from another substance

Question 10

What is a conjugate acid and conjugate base?

Answer 10

CA: Particle formed when a base gains hydrogen ion
CB: Particle that remains when an acid has donated a hydrogen ion

Question 11

What is an acid and base according to Lewis?

Answer 11

Acids accept a pair of electrons while bases donate a pair

Question 12

What happens when acids and bases react with metals?

Answer 12

Acids: Form metal salts and release hydrogen gas
Bases: Release hydrogen gas
