Question

How to determine the titre value without performing titration?

Answer 1

chemistry to figure out the amount of a chemical in a solution. This chemical is called the titrand. To figure out the amount of titrand in the solution, a known amount of a different chemical is added to the titrand's solution; this chemical— called the titrant, or titrating solution—reacts with the titrand. By measuring how much of the titrating solution is needed to react with all of the titrand in the solution, you can calculate how much titrand was in the solution. Simply put:

Titrand: A chemical you want to know the quantity of in your sample.
Titrant (titrating solution): A chemical you add, in a known quantity, to react with the titrand and to help you calculate the quantity of the titrand in your sample.
The point at which all of the titrand has reacted is called the endpoint, or equivalence point. How do you know when the endpoint has been reached? At the endpoint, there is usually a color change in the titrand's solution. This is caused by an indicator, which is included in the titrand's solution just so you can see when you have reached the endpoint. The unknown amount of titrand in the titrand's solution can usually be determined by setting up a proportion with the known amount of titrating solution that was added. How this is done depends on the exact titrating reaction that is being used.
