Oh thats pretty simple that is a gastroenterologist
Answer:The ratio of the concentrations of
and
when the buffer has a pH of 7.02 is 0.69
Explanation:
The dissociation constant for formic acid =
Concentration of HA= 0.5 mM
Concentration of
= 0.1 mM
pH = 6.16
First we have to calculate the value of
.
Using Henderson Hesselbach equation :
Now put all the given values in this expression, we get:
To calculate the ratio of the concentrations of
and
when the buffer has a pH of 7.02.
Using Henderson Hesselbach equation :
Thus the ratio of the concentrations of
and
when the buffer has a pH of 7.02 is 0.69
