Answer
is: <span>the
percent ionizationof formic acid is 1,82%.
Chemical reaction: HCOOH(aq) </span>⇄ H⁺(aq)
+ HCOO⁻(aq).<span>
pKa(</span>HCOOH) = 3,77.
Ka(HCOOH) = 1,7·10⁻⁴.
c(HCOOH) = 0,5 M.
<span>
[H</span>⁺]
= [HCOO⁻] = x; equilibrium
concentration.<span>
[HA] = 0,1 M - x.
Ka = [H</span>⁺] · [HCOO⁻] / [HCOOH].<span>
0,00017 = x² / 0,5 M - x.
Solve quadratic equation: x = 0,0091 M.
α = 0,0091 M ÷ 0,5 M · 100% = 1,82%.</span>
