Acids and Bases

Question 1

What are the 7 properties of Acids?
(produce, taste, corrosion, *, reaction, pH, litmus paper)

Answer 1

• Produce H+ (as H₃O+) ion in water
• Taste sour
• Corrode metals
• Electrolytes
• React with bases to form salt and water
• pH less than 7
• turns blue litmus paper red

Question 2

How do you name acids that start with H

Answer 2

**If has TWO elements: **
- Use hydro-
- Use -ic

If has THREE+ Elements:
- NO hydro-
- Use -ic

Question 3

Name: HCl (aq)

Answer 3

Hydrochloric acid

Question 4

Name: HI (aq)

Answer 4

Hydroiodic acid

Question 5

Name: H₂CO₃ (aq)

Answer 5

Carbonic acid

Question 6

Name: H₂SO₄ (aq))

Answer 6

Sulfuric acid

Question 7

Name: HCl

Answer 7

Hydrogen chloride

Because there is no (aq) to denote that it is a solution, it cannot be an acid/base. Therefore, we would name it like normal.

Question 8

Acids usually have ______, while bases usually have ______

Answer 8

H+
OH-

Question 9

How do you calculate the pH of [H+], given H+ and pOH given OH-

Answer 9

pH = -log[H+]
pOH = -log [OH-]

Question 10

Given solution [H+] = 0.01M, calculate its pH

Answer 10

pH = -log [0.01M]
= 2.0 OR 1.0 x 10⁻²

Question 11

Given solution [H+] = 0.01M, calculate is pOH

Answer 11

1) Find pH = 2.0
2) Find pOH by using pH -> 14 - 2 = 12
3) pOH = 12

Question 12

Given pH of 3.0, find the H+ ion concentration

Answer 12

10^(-3) = 0.001M

Question 13

Given pOH of 8.0, find the OH- ion concentration.

Answer 13

10^(-8) = 0.00000001M

Question 14

Given pOH of 8.0, find the H+ concentration.

Answer 14

1) Find pH by doing 14 - 8 = 6
2) use log inverse to find H+ concentration = 10 ^ (-6) = 0.000001M
