Question

In which of the following titrations would the solution be neutral at the equivalence point? [Hint: For a neutral equivalence point, we need both a strong acid and a strong base as analyte and titrant, respectively.]

HOCl titrated with Ba(OH)₂

CH₃COOH titrated with NaOH

HClO₄ titrated with KOH

Sr(OH)₂ titrated with H₃PO₄

NH₃ titrated with HCl

Answer 1

Following is the - complete Answer -&- Explanation: for the given: Question, in.....typed format....

$\Rightarrow$Answer:

Option - ( c ): HClO4 titrated with KOH.

$\Rightarrow$Explanation:

Followingis the complete Explanation, for the above Answer...

• Step - 1:

We know for a solution to be neutral - at its equivalence point, we require, both the anylate, and the titrant to be strong acid, and strong base, respecively... Now, we will have to check, if any of the given options, satisfy the above mentioned criteria, and therefore will give us our answer...

• Step - 2:

​​​​​​​Following is what we can find about the given options, we have in the question, in the form of a table:

Options ID	Anylate ( acid / base )	Type of Anylate	Titrant ( acid / base )	Type of Titrant
Option - ( a )	HOCl ( hypochlorous acid )	weak acid	Ba(OH)2 ( barium hydroxide )	strong base
Option - (b)	CH3COOH ( acetic acid )	weak acid	NaOH ( sodium hydroxide )	strong base
Option - (c)	HClO4 ( perchloric acid )	strong acid	KOH ( potassium hydroxide )	strong base
Option - ( d )	Sr(OH)2 ( strontium hydroxide )	strong base	H3PO4 ( phosphoric acid )	weak acid
Option - (e)	NH3 ( ammonia )	weak base	HCl ( hydrochloric acid )	strong acid

• Step - 3:

​​​​​​​Therefore, as we can see above, the given: Option - (c), as shown in deep brown color is the only option, which satisfies the condition, mentioned in Step - ( 1 ). Therefore, we can certainly say that our answer, would be nothing other than Option - (c), which would satisfy the desired conditions.
