Question

During an acid-base titration, when do the contents of the beaker consist of only water, a salt, and a trace of indicator?

Answer 1

The end point of titration or the point of neutralization.

Step-by-step explanation:

A quantitative analysis which is used to determine the concentration of an acid or a base by exactly neutralizing it with a standard solution of base or acid having known concentration is the acid base titration.

This reaction produces a salt and water with a trace of indicator at the end point of titration which is also called the point of neutralization.

Answer 2

In acid base titration an acid neutralized by a base or a base is neutralized by acid (both are neutralized by each other).

one common reaction is

`HCl + NaOH --> H_(2)O + NaCl`

In titration we fill burette with either acid or base and and take other in flask.

When we start adding solution from burette to flask, neutralization starts. At the ponint of complete neutrlization all the acid / base neutralized base /acid.

This point is when the content of flask or beaker consists of only water, salt and trace of indicator

Thus answer is point of neutralization.
