What is the pH of a solution that is 0.500 M in acetic acid and 1.00 M in CH3COONa? Ka = 1.75*10-5 Group of answer choices 4.47 5.06 4.77 0.3 Flag this Question

Explanation:

Considering the Henderson- Hasselbalch equation for the calculation of the pH of the buffer solution as:

pH=pKa+log[base]/[acid]

Where Ka is the dissociation constant of the acid.

Given that the acid dissociation constant = 1.75×10⁻⁵

pKa = - log (Ka) = - log (1.75×10⁻⁵) = 4.76

Given concentration of acid = [acid] = 0.500 M

[Base] = 1.00 M

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

1. they vary with a higher number because boiling is way hotter than melting
