Answer:
The percentage of amine is protonated is 63,07%
Explanation:
The reaction of an amine RNH₃ (weak base) with water is:
RNH₃ + H₂O ⇄ RNH₄⁺ + OH⁻
The kb is defined as:
As kb = 4,004x10⁻⁵ and [OH⁻] is :
1,708 = [RNH₄⁺] / [RNH₃] <em>(1)</em>
As the total amine is a 100%:
[RNH₄⁺] + [RNH₃] = 100% <em>(2)</em>
Replacing (1) in (2):
1,708 [RNH₃]+ [RNH₃] = 100%
2,708 [RNH₃] = 100%
[RNH₃] = 36,93%
Thus,
<em> [RNH₄⁺] = 63,07%</em>
The percentage of amine protonated is 63,07%
