Acids And Bases

Question 1

Bronsted-Lowry def of an acid

Answer 1

Proton donor

Question 2

Answer 2

Proton acceptor

Question 3

What is a proton?

Answer 3

Positively charged hydrogen ion

Question 4

Conjugate base

Answer 4

Substance formed when the proton is removed

Question 5

Strong acid

Answer 5

Completely ionizes in solution (ex HCl)

Question 6

Weak acid

Answer 6

Does not completely ionize in solution (ex. HF)

Question 7

Double arrow indicates what kind of reaction?

Answer 7

A reversible reaction

Question 8

Six strong acids

Answer 8

HCL, HBr, HI, HNO₃, HClO₄, H₂SO₄

Question 9

Why is HF a weak acid?

Answer 9

The hydrogen bond is pretty strong, and does not want to break the bond

Question 10

Strong base

Answer 10

One that completely dissociates in solution (the hydroxides of group one and two)

Question 11

Weak bases produce what ion?

Answer 11

OH^-, this is indicative of a weak base

Question 12

Organic amines are what kinds of bases?

Answer 12

Weak bases

Question 13

Amphoteric

Answer 13

Can act as either an acid or a base (water is an example!)

Question 14

What are the pairings with acids, bases, and conjugates?

Answer 14

Acid-base conjugate, base-acid conjugate

Question 15

What is the ion product constant for water?

Answer 15

1.0x10^-14

Correct for all kimnds of water (acidic, neutral, etc.)

Question 16

Ion constant for pure water

Answer 16

1.0x10⁷

Question 17

pH of a acidic solution

Answer 17

pH < 7

Question 18

pH of a basic solution

Answer 18

pH > 7

Question 19

mathematical def of pH

Answer 19

pH = -log[H⁺]
[H⁺] = 10^-pH
