Indicators change the colours when the PH of the sample changes. So during titration when the reaction is complete a new product will form which is resulting in sudden change of PH. This can be detected by the change in the colour of the sample. The reaction may be neutralization reaction or Redox reaction. So to know the exact stoichiometric quantity of reagents to complete a reaction we must use Indicators. different indicators give different colours based on the PH.
Indicators are important in volumetric analysis because they help signal the endpoint of a titration by changing color when the reaction is complete. This allows for accurate and precise measurements of the volume of titrant needed to react completely with the analyte. Indicators help ensure the titration is carried out to completion and provide a visual signal for when to stop the titration process.

What is molarity ..volumetric analysis?
Molarity is a measure of the concentration of a solution, representing the number of moles of solute per liter of solution. In volumetric analysis, it is important for accurately measuring the volume of solutions to determine the concentration of a solute using techniques such as titration. By knowing the molarity of a solution and the volume used in the analysis, you can calculate the amount of substance present in the sample being tested.
What precise volumetric equipment is used in titrations?
In titrations, precise volumetric equipment like burettes and volumetric flasks are commonly used. Burettes are used to deliver precise volumes of titrant, while volumetric flasks are used to prepare accurate standard solutions or to collect titrated solutions for analysis.
Why titration is called volumetric analysis?
Titration is called volumetric analysis because it involves measuring the volume of a solution (titrant) of known concentration that reacts completely with a measured volume of another solution (analyte) of unknown concentration. By determining the volume required to reach an endpoint, the concentration of the analyte can be calculated.
What is the definition for complexometric titrations?
Complexometric titrations are a type of volumetric analysis that involves the use of a complexing agent (such as EDTA) to form stable complexes with metal ions in solution. By titrating with a solution of known concentration of the complexing agent, the endpoint of the reaction can be determined based on a color change or other indicator, allowing for the quantitative determination of the metal ion concentration.
Is borax a primary standard?
No, borax is not considered a primary standard. Primary standards are highly pure reagents that can be used to standardize solutions for volumetric analysis, while borax is typically used as a secondary standard for acid-base titrations.

Why we use indicator in the volumetric analysis?
Indicators are used in volumetric analysis to signal the end point of a reaction. They change color at a specific pH or stoichiometric point, indicating when the reaction is complete. This helps in determining the volume of titrant needed for complete reaction with the analyte.

What is the difference between volumetric analysis and gravimetric analysis?
AnswerVolumetric analysis or titration is a common laboratory method of chemical analysis which can be used to determine the concentration of a known reactant; volumetry is a quantitative method of analysis.Qualitative analysis is used to separate and detect elements, functional groups, molecules etc. in a sample substance, without specifying concentration.
How does temperature variation effect volumetric measurements?
When temperature increase the volume also increase; but if you think to volumetric titrations the effect is without importance.
