Acid Base

Question 1

Adding more volume of the same concentration does what to the pH?

Answer 1

Nothing, pH is unchanged.

Question 2

What is the pH if [H+] = 0.1 M?

Answer 2

pH = -log [H+]

pH = -log [1 x 10^-1] = 1

Question 3

pH + pOH = ?

Answer 3

14

Question 4

If an acid has a very stable conjugate base, it is ________?

Answer 4

Strong / more acidic

Question 5

Logarithm equation

Answer 5

pH = -log [H+]

pOH = -log [OH-]

Question 6

Kw =

Answer 6

Kw = [H+][OH-] = 10 ^-14

Question 7

Ka =

Kb =

Answer 7

Ka = [H₃O⁺][A^-] / [HA]

Kb = [OH^-][B⁺] / [BOH]

Question 8

Henderson-Hasselbach

Answer 8

pH = pK_a + log [congugate base] / [weak acid]

pOH = pK_b + log [congugate acid] / [weak base]
