Dilution is the process of adding a solvent, usually water, to a solution in order to decrease the concentration of a solute. This is important in experiments because it allows for the creation of solutions with specific concentrations that are necessary for accurate measurements and reactions.
The formula for calculating dilution is M1V1 = M2V2, where M1 is the initial concentration, V1 is the initial volume, M2 is the final concentration, and V2 is the final volume. In this case, you would rearrange the formula to solve for V2, which would be the volume of water to add. So, V2 = (M1V1)/M2.
The initial concentration refers to the concentration of the solution before any dilution occurs. In this case, the initial concentration of 0.01M HCN is 0.01 moles per liter (mol/L) or 0.01 molar (M).
No, not all solvents are suitable for dilution. The solvent used for dilution should be able to dissolve the solute and not react with it. In most cases, water is used as a solvent for dilution because it is a polar molecule and can dissolve many solutes.
When performing a dilution, it is important to use precise measuring equipment and follow the correct ratio of solute to solvent. It is also important to mix the solution thoroughly after dilution to ensure that the concentration is evenly distributed. Additionally, any spills or mistakes should be cleaned up immediately to avoid contamination or inaccurate results.
