Question

Calculate the percent ionization in each of the following solutions. (a) 0.10 M NH3 WebAssign will check your answer for the correct number of significant figures. % (b) 0.010 M NH3 WebAssign will check your answer for the correct number of significant figures. % (c) 0.10 M CH3NH2 WebAssign will check your answer for the correct number of significant figures. %

Answer 1

Answer:

Dissociation NH3 0.10 M : 1.2%

Dissociation NH3 0.010 M : 3.9%  

Dissociation CH3NH2 0.10 M : 6.5%

Explanation:

Hello!

To calculate the percentage of dissociation it is necessary:

Pose the balanced chemical equation.

Pose the equilibrium constant.

Calculate the value of "x"

Calculate the percentage of dissociation.

By having the concentrations given two significant figures we express the dissociations with the same amount of significant figures.
