What is the function of an indicator in titration?
Change color
What structure of phenolphthalein indicator and the reaction of the color exchange in the titration?
hc20h1354
What changes color at the endpoint of titration?
change in pH, changes the colour (of the indicator)
When do you know endpoint of titration?
when the colour of the indicator used is the color it should be in neutral
When to use back-titration instead of direct titration?
When you have passed the tipping point and the color indicator turns from it's color to the clear color of the original solution. Then you back titrate to color again.

What are two ways to identify the equivalent point in a titration?
- using a color indicator- by potentiometry
What is a function of an indicator in a titration?
The function is to change color. This happens when all the H+ ( or H3O+) from the acid has been neutralized, an indicator in the sample will change
Why is important that the indicator is present in the solution during the course of titration?
the reason why a indicator is important in some titration is to show a change in the solution. for example as a solution runs from acidic to basic the indicator may turn a different color. but this is the reason why it is important inmost experiments.
What happens during an acidic base titration in the presents of an indication?
The indicator will change color as the pH changes.
If the equivalence point of a titration is 5 what range of pH should the indicator be?
The indicator should change color right at the equivalence point, so 5.
What is auto indicator?
Auto indicator is a substance which remaining in a titration as a standard solution or a distandard solution shows ending point of a reaction by changing its color.
What does a color change in an acid-base titration mean?
according to change of PH of medium where the indicator color is changed according to PH of medium
