What is the molarity of a naoh solution if 11.9 ml of a 0.220 m h2so4 solution is required to neutralize a 25.0-ml sample of the naoh solution?

Answer : The concentration of the is, 0.209 M

Explanation :

Using neutralization law,

where,

= basicity of an acid = 2

= acidity of a base (NaOH) = 1

= concentration or molarity of = 0.220 M

= concentration or molarity of NaOH = ?

= volume of = 11.9 ml

= volume of NaOH = 25.0 ml

Now put all the given values in the above law, we get the concentration of the .

Therefore, the concentration of the is, 0.209 M

it should be p1 v1 = p2 v2

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
