FREE Expert Solution

Kb of aniline (C6H5NH2) is 4.3x10-10

(1) Setup an ICE chart


(2) Setup Kb expression

Kb=productsreactants=[OH-][C6H5NH3+][C6H5NH2]


Solving for x = [OH-]


Kb=4.3x10-10=[OH-][C6H5NH3+][C6H5NH2]4.3x10-10=[x][x][0.26- x], ignore -x:[C6H5NH2]Kb>5004.3x10-10(0.26)=x2x = 4.3x10-10(0.26)
