Benzoic acid has Ka =6.5× 10 ?5 , and citric acid has Ka =7.2× 10 ?4. What is the stronger conjugate base?
likoan [24]

Answer: The stronger conjugate base is, Citric acid.

Explanation :

The value of dissociation constant of Benzoic acid is higher than the citric acid. This means that the acid will readily dissociate and stronger will be the acid. Higher the value of dissociation constant of an acid weaker will be its conjugate base and the lower value of dissociation constant of an acid means that the stronger will be its conjugate base.

Therefore, the stronger conjugate base is Citric acid.

Makovka662 [10]

Answer:

33.8 g Solution

Explanation:

A chemistry student needs 15.0 g of methanol for an experiment. The concentration of ethanol in the solution is 44.4% w/w, that is, there are 44.4 g of methanol every 100 g of solution. The mass of solution that would contain 15.0 g of methanol is:

15.0 g Methanol × 100 g Solution/44.4 g Methanol = 33.8 g Solution

Since 33.8 g are required and 320. g are available, there is enough solution for the requirements.
