Answer 2

Standard Solution

Explanation:

• A solution whose concentration is accurately known is called a Standard Solution.
• All the components present in the standard solution are precisely weighed and calculated.
• The concentration of the standard solution can be expressed in molarity (M) that is moles per litre (mol/L).
• Solute with accurate mass are weighed and their molar concentration is calculated which is dissolved in the specific volume of the solution.
• These solution are mainly used in determination of the molar concentration of unknown solution with help of titration.
