Question

Determine the normality of the given hcl solution by titrating it against N/20 Naco3 solution

Answer 1

Explanation:

uuuuuuuuuuuuuuuuuuuuuuuuuuuu

Answer 2

Volume of pipette = 25 mL

Volume of NaOH = 25 mL

Strength of NaOH = N/20

Let the titre value be V.

Using the normality equation,

At the point of equivalence

Normality x volume of NaOH = normality x volume of HCl

N/20 x 25 mL = Normality of HCl x titre value.

If we know the titre value, the strength of HCl in normality can be known.
