Chapter 19: Acids

Question 1

Arrhenius: An acid is a substance that produces only:

Answer 1

Hydrogen [H+] ions in solution.

Question 2

Arrhenius: and a base is a substance that produces:

Answer 2

Only [OH-] ions in the solution.

Question 3

Bronsted: an acid is a substance that:

Answer 3

Hydrogen ion donor.

Question 4

Bronsted: and a base is a substance that:

Answer 4

Hydrogen ion acceptor.

Question 5

What are some examples of Arrhenius acids?:

Answer 5

HCL, CH3COOH, H2SO4, HC2H3O2

Question 6

What are some examples of Arrhenius base?:

Answer 6

KOH, Ca(OH)2, NH3

Question 7

Why are acids and bases good electrolytes?

Answer 7

They produce ions that move freely.

Question 8

Properties of Acids:

Answer 8

Taste sour, produce [H+] ions, aqueous solution produces electrolytes.

Question 9

Properties of bases:

Answer 9

Taste bitter, Slippery, produces [OH-], aqueous solution produces electrodes.

Question 10

Bronsted:

Answer 10

defines an acid as a hydrogen ion donor and base as a hydrogen ion acceptor.

Question 11

Organic acids:

Answer 11

contain carboxyl group

Question 12

COOH:

Answer 12

Organic acids.

Question 13

Acid:

Answer 13

PH lower than 7

Question 14

Base:

Answer 14

PH higher than 7

Question 15

AS PH in decreases by 1 point the solution has:

Answer 15

becomes more acidic, has 10 times more H30 ions

Question 16

As PH increases by 1 point:

Answer 16

becomes more basic, 10 times more OH ions

Question 17

An electrolyte when dissolved in water:

Answer 17

conducts electricity, must have moving charged particles.

Question 18

Metals are good conductors because of:

Answer 18

Sea of electrons. (allows ions to move free)

Question 19

Ionic substances are good conductors because:

Answer 19

Dissociated ions are free to move.

Question 20

Acids and bases are also electrolytes because they either:

Answer 20

have or produced ions that can move in solution.

Question 21

An Indicator is a substance that:

Answer 21

changes color depending on PH of solution.
