Question

The dissociation constant of acetic acid is 0.000018 and that for cyanoacetic acid is 0.0036 at 298 K.
What would be the ratio of volumes of the two acid solutions, each containing equal moles of the acids,
so that the solutions become isohydric?

Answer 1

Answer:

sorry I didn't know the isohydric

Answer 2

Answer:

ishydric means both acid have same ph

given ----number of moles constant (n)

ph = - log(H+)

- log(H+) = - log(H+) let take d.o.d symbol a

of acetic of cynoacetic

acid acid

(na/v) = (na'/v') where n is no. of moles

v &v' volume of respective

solution

(18×10^-6/v) = ( 36×10^-4/v')

v:v' = 1:200
