The acid-dissociation constant, Ka, for benzoic acid is 6.5 × 10-5. Which will you use to calculate the base-dissociation constant, Kb, for the conjugate base of benzoic acid?

Answers

Answer 1

Answer:

Answer:

The base-dissociation constant, Kb,for the conjugate base of benzoic acid is :

$K_(b)=1.54* 10^(-10)}$

Explanation:

The product of acid dissociation constant and base dissociation constant is equal to the water dissociation constant.The general formula for the reaction is:

$K_(w)=K_(a)K_(b)$

For the acid dissociation reaction:

$HA + H_(2)O\rightleftharpoons H^(+)+A^(-)$

The conjugate base for the acid is A-

The acid is HA . and its Ka is given.

The value of Kw is fixed at a given temperature , which is equal to:

$K_(w)=10^(-14)$

$K_(a)=6.5* 10^(-5)$

$K_(b)=(10^(-14))/(6.5* 10^(-5))$

$K_(b)=1.54* 10^(-10)}$

Answer 2

Answer:

Ka*kb=kw

Explanation:Got it right

A saturated solution of NaNO3 is prepared at 60.°C using 100. grams of water. As this solution is cooled to 10.°C, NaNO3 precipitates (settles)out of the solution. The resulting solution is saturated. Approximately how many grams of NaNO3 settled out of the original solution?
(1) 46 g (3) 85 g
(2) 61 g (4) 126 g

Answers

The answer is 46 g

The explanation :

According to the attached curve of the relation between the temperature and the grams in solutions:

-we can see from the curve that the grams of NaNO3 at 60°C = 126 g

-and the grams of NaNO3 at 10°C = 80 g

-so, To get the grams of NaNO3 settled out of the original solution, we will subtract the grams of NaNO3 at 10°C - the grams of NaNO3 at 60°C

126 g - 80 g = 46 g

∴ the correct answer is 46 g

The answer is (1) 46g. This is related to the solubility curve of the NaNO3. The solubility of NaNO3 under 60 ℃ is 126 g. And the solubility under 10 ℃ is 80 g. So the NaNO3 precipitates is 126-80=46 g.
