What changes color at the endpoint of titration?
change in pH, changes the colour (of the indicator)
Why is a white tile used in an acid - base titration?
It makes it easier to see the colour change in the solution after it reaches its endpoint.
When do you know endpoint of titration?
when the colour of the indicator used is the color it should be in neutral
Changes color at the endpoint of a titration?
yes,its true that colour changes at the endpoint of titration but in some cases coloured solution become colourless.it indicate end of a reaction in which one substance has been fully used up.indicators are used to locate the endpoint but in certain cases reactant or product itself is coloured which at endpoint become colourless or coloured.
The purpose of an indicator in a titration experiment?
The indicator is used to measure the end point of titration. Methyl red and phenolphthalein are frequently used indicators in acid-base titration. Potassium permanganate can used as a self indicator in redox titrations where applicable.

When approaching the endpoint for titration how can you tell that you are very close?
when the colour persists/ stays for a longer period of time before going colourless again
What is the colour change in the titration of KOH with H2SO4 using methyl orange as the indicator?
orange
Why do permanganate titration should be done in acidic solution?
coz the oxidation state of manganese ion changes from +7 to +4. as a result Mno2 is formed which is brown in colour hence titration colour change cannot be detected
What is the colour of the endpoint for sodium hypochlocrite and potassium iodide?
The endpoint color of sodium hypochlocrite and potassium iodide is not listed.
What is the purpose for using phenolphthalein for an acid base titration?
It's the colour indicator you watch for during the titration.
What is the colour change in the titration of NaOH and C2H2O4 if using phenolphthalein as an indicator?
Adding NaOH-sol'n to oxalic acid, C2H2O4, the colour (from colorless) has to become purple-blue at pH 8 to 10.
Can you have viva questions on titration?
pink colour obtain on titration with potesium dicromate by using indicater n phanyl anthronilic
