Question

The ionization constant of dimethylamine is 5.4 × 10^–4 . Calculate its degree of ionization in its 0.02 M solution. What percentage of dimethylamine is ionized if the solution is also 0.1 M in NaOH? 

Answer 1

Now, if 0.1 M of NaOH is added to the solution, then NaOH (being a strong base) undergoes complete ionization. 

It means that in the presence of 0.1 M NaOH, 0.54% of dimethylamine will get dissociated.
