Question

Why is it logical to assume that they hydrogen ion concentration in an aqueous solution of a strong monoproctic acid equals the molarity of the acid?

Answer 1

assume HA thetrong monoproctic acid
assume Co initial concetration
HA -> A- + H+
Co 0 0
-a*Co +a*Co +a*Co
(1-a)*Co a*Co a*Co
for a strong monoproctic acid
\[a \approx1\]
so \[\left[ H+ \right]\approx Co\]

Answer 2

what is the name of that a i used??
