Question

Deterrmine the normality of the guven hcl solution by titrating it against n/20 naoh solution

Answer 1

The data given here is insufficient. There must be the involvement of the volume of NaOH.

Also, the Volume of the HCl also must be noticed in a Pipette while performing the experiment of Titrations.

Now, Let us say that the volume noticed be 'V' ml and normality of the solution be N₁.

Also, the volume of the NaOH solution given be V₁ and Normality is 20. [Given].

Now, Using the Formula,

N₁V₁ = N₂V₂

⇒ 20 × V₁ = N₂ × V₂

∴ N₂ = 20 × V₁/V₂

Hence, the Normality of the HCl can be calculated from this formula.

Hope it helps.

This is the basic question of the Titration experiment of Class 11th Standard.

You need to notice the Volume the HCl at least 5 times then the value which is repeated the most will be considered as the volume for the calculation of Normality. Also, the volume of the NaOH used must be given in the question. [Data Insufficient].

Hope it helps.
