)
, where 
is the dissociation constant of weak base and 
is the concentration of weak base. Ethyl ammonium ion is acid which will dissociate into H⁺ ion and ethyl amine. 
of ethylammonium ion is given as 10.70. Concentration is given as 0.1 m.![[H^{+} ]= (K_{a} C_{a})^{\frac{1}{2}}, where K_{a}](/tpl/images/0078/0733/67e9f.png)
is dissociation constant of acid. 
=10.70
=1.99 X

=(
X0.1)=1.99X
. 
= -log
=11.7
