Ammonia (NH3) is a weak base that reacts with a strong acid to form the ammonium ion, NH4 . In the titration of 15.00 mL of an ammonia cleaner with 0.5000 M HCl, 42.6 mL of the titrant was required to reach the endpoint. What is the concentration of the NH3 in solution

The concentration of the in solution is 1.42 M

Explanation:

According to neutralization law:

where,

= basicity of = 1

= acidity of = 1

= concentration of = 0.5000 M

= concentration of  = ?

= volume of = 42.6 ml

= volume of = 15.00 ml

Now put all the given values in the above law, we get:

By solving the terms, we get :

Thus the concentration of the in solution is 1.42 M
