In titration, in general, we measure the concentration of the analyte with the help of another chemical substance of known concentration called titrant. We take the analyte in the conical flask and we take the titrant in burette.
To know whether the reaction of analyte and titrant is complete or not we take the help of an indicator. The indicator changes color at the point when the reaction is complete or in other words when the reaction reaches end point. Either it becomes colored from colorless or vice versa. Thus the purpose of the indicator is to determine when the end point has been reached.
Thus the above statement is true.

Poits The purpose of the indicator is to determine when the end point of the reaction has occurred. True False
Colours of phenolphthalein indicator 100 Alkaline End-point True False 1. The phenolphthalein indicator is not affected by the pH of the solution. 2. The phenolphthalein Indicator changes colour close to the point of neutralisation which shows the end-point of the titration, 3. When adding acid to base the phenolphthalein indicator changes colour from colourless to pink at the end of the titration Titra Acids and alkalis

What type of reaction occurred when AgNO3 was mixed with K2CrO4? point Single displacement Decomposition reaction Combination reaction Double displacement Combustion reaction
True or False: A reaction with an increase in entropy and AG<O will only occur when energetically coupled with an exergonic reaction.
For each of the following statements, determine if it is TRUE or FALSE. If false, explain why or rewrite the statement such that it is true. 1. Reactions generally start at equilibrium and stay there. 2. In cells, the product of one reaction is often the substrate for another reaction. 3. The energy of reactants at the start of an uncatalyzed reaction is different from the energy of reactants at the start of a catalyzed reaction. 4. An uncatalyzed reaction...
Determine whether the statements are true or false and sort into the appropriate bins. True False Opposite poles repel. Heating a magnet makes it stronger When two nearby electrons in a material have opposite spins, their contributions to the local magnetic field tend to add up. When a magnet is broken in half, you end up with two smaller magnets. Magnetic domains are present even in an unmagnetized piece of iron. Every electron in an atom behaves like a tiny...
