Question

Acid base titration curve interpretation

i would like to know what's present at each parts of the curve from the titration curve.

014 (part 1 of 3) 10.0 points Below is the pH curve of a weak acid (HA) titrated with strong base. Answer the fol- lowing question based on the interpretation of this pH curve. Be as accurate as possible. Titration Curve --wooco 0 5 10 15 20 25 30 35 40 45 50 55 60 Amount of Base added (mL.) What is the pH at the equivalence point of this titration? Answer in units of pH

Answer 1

This is a Titration curve of a weak acid and a strong base

During this titration we have firstly weak acid present at pH around 2

And after we finish our standardization the curve ends at about ph 9

And the point where we can call equivalence point is around 35 ml and pH 6 approximately

The curve before it is called before equivalence curve and curve after it is called after equivalence curve.

Before the equivalence curve the solution is acidic it becomes neutral at equivalence point then again it starts to become basic due to addition of a strong base.

The point at around and 15 ml can be considered as half equivalence point approximately.

I hope this helps. If you have any query or want more detailed explanation, feel free to ask in the comments section below
