The degree of dissociation of acetic acid in 0.1 M solution is 0.04 . Calculate K_a for acetic acid. Where alpha is the degree of dissociation,C is the concentrationof the acid in moles/ lit. |

Answer» SOLUTION :`K_a=(alpha^2 C)/(1-alpha)=(02xx.02xx0.1)/(1-0.02)` `K_a=(0.4xx10^(-4))/(0.98) = 4.08xx10^(-5)` |
