Acids And Bases

Question 1

Name 3 strong acids

Answer 1

1. HCl
2. H2SO4
3. H3PO4

Question 2

Name 3 strong bases

Answer 2

1. NaOH
2. KOH
3. Mg(OH)2

Question 3

Is pH the same as strength of acid/base

Answer 3

NO

Question 4

What does increased strength mean

Answer 4

Increased:
- reaction rate
- conductivity
- concentration of ions forming

Question 5

What does neutralization point NOT mean

Answer 5

≠ ph is 7
≠ H30+ concentration is equal to OH- concentration

Question 6

What does the hydrolysis product mean

Answer 6

H30+ in product = acidic

OH- in product = basic

Question 7

Acid reactions: acid + metal

Answer 7

= Salt + H2

Question 8

Acid reactions: acid + metal hydroxide

Answer 8

= salt + H2O

Question 9

Acid reactions: acid + metal oxide

Answer 9

= salt + H2O

Question 10

Acid reactions: acid + metal carbonate

Answer 10

= salt + CO2 + H2O

Question 11

Acid reactions: acid + metal hydrogen carbonate

Answer 11

= salt + CO2 + H2O

Answer 12

Methyl orange

Question 13

What indication for neutral (pH ≈ 7)

Answer 13

Bromothymol blue

Question 14

What indicator for acidic (high pH)

Answer 14

Phenolphthalein
