Question

The chemical reagent from which solution of required concentration can be prepared is

Answer 1

The chemical reagent from which solution of required concentration can be prepared is known as STANDARD SOLUTION.

Explanation:

For the preparation of the solution, we require following

• A Chemical reagent is prepared from the solution with a known concentration.
• A Solution with a known concentration is called a standard solution.
• It is used in titration, where the strength of the unknown solution is determined with the use of the solution of the substance of known concentration.
• the concentration of a standard solution is expressed in molarity or moles per litre.
• Concentration is the number of solutes dissolved in a litre of solution.
