The volume of stock solution refers to the amount of concentrated solution that is used to prepare a diluted solution. It is typically measured in units of milliliters (mL) or liters (L).
The volume of stock solution can be calculated using the dilution equation: M1V1 = M2V2, where M1 is the initial concentration of the stock solution, V1 is the initial volume of the stock solution, M2 is the final desired concentration, and V2 is the final desired volume. Rearranging the equation, V1 = (M2V2)/M1.
A stock solution is used to prepare solutions of specific concentrations for experiments. It allows for precise and accurate measurements of the desired concentration, as well as reducing the amount of time and effort needed to prepare multiple solutions.
To prepare a stock solution, you will need to measure out the desired amount of solute (usually in grams or moles) and add it to a volumetric flask. Then, add enough solvent (usually water) to reach the desired final volume. The solution should be thoroughly mixed to ensure homogeneity.
Yes, the volume of stock solution can be adjusted by adding more solvent to increase the volume or by evaporating some of the solvent to decrease the volume. However, this will also affect the concentration of the stock solution, so it is important to recalculate the new concentration using the dilution equation.
