Salts, Buffers, Titration, and Solubility

Question 1

How are acid and base strengths determined?

Answer 1

By determining the equilibrium constant of the substance when it dissolves in water.

Question 2

As the equilibrium approaches the product side, what happens to the strength of the acid and base?

Answer 2

It increases.

Question 3

As attraction increases, what happens to the strength of the acids and bases?

Answer 3

Acids get weaker, bases get stronger.

Question 4

As attraction increases, what happens to the strength of the acids and bases?

Answer 4

Acids get weaker, and bases get stronger.

Question 5

The _______ an acid is at donating an H+ ion, the weaker the conjugate ______ is at accepting an H+ ion.

Answer 5

stronger, base.

Question 6

The strength of a conjugate is the ______ of what it starts as.

Answer 6

opposite.
ex: SA ——>WB.
ex: WA —–> SB.

Question 7

What are the characteristics of a neutral salt solution?

Answer 7

1. The salt’s cation is the conjugate acid of a strong base.
2. The salt’s anion is the conjugate base of a strong acid.

Question 8

What are the characteristics of a basic salt solution?

Answer 8

1. The salt’s cation is the conjugate acid of a strong base.
2. The salt’s anion is the conjugate base of a weak acid.

Question 9

What are the characteristics of an acidic salt solution (case 1)?

Answer 9

1. The salt’s cation is the conjugate acid of a weak base.
2. The salt’s anion is the conjugate base of a strong acid.

Question 10

What are the characteristics of an acidic salt solution (case 2)?

Answer 10

1. The salt’s cation is a highly charged metal ion.
2. The salt’s anion is the conjugate base of a strong acid.

Question 11

The pH of the salt solution depends on the relative_______ of the weak acid and weak bases.

Answer 11

strengths
