What should you do during a titration when you notice the indicator start to indicate the approach of the equilibrium point? Add the second reactant faster. Add the second reactant slower. Add more indicator.

Respuesta :

B. Add the second reactant slower.

Answer:

Add the second reactant faster.

Explanation:

In titration we take, we take a reactant (titrand) in conical flask. The second reactant (titrant) is filled in burette.

Now we add indicator in the first reactant (taken in flask) and start adding the second reactant from burette.

The reaction starts and when it appears that we are approaching the end point, we start adding the second reactant slower, in order to avoid missing the end point. If we add the second reactant fast, it may lead to addition of excess of reagent and thus may affect our calculations and readings.
