Expert Solution
Step 1
The process of dilution is defined as the process in which a solution with a lower concentration is prepared from a solution with the higher concentration by adding an appropriate amount of water.
When a dilute solution is made, more solvent is added. The number of moles of the solute does not change, what changes is the concentration.
The dilution equation is,
M1V1 = M2V2
- M1 and V1 are the molar concentration and volume of the initial concentrated solution.
- M2 and V2 are the molar concentration and volume of the final dilute solution.
