To prepare a solution using solid and DI water, first measure out the desired amount of solid using a balance. Then, add the solid to a flask and add a small amount of DI water to dissolve the solid. Once the solid is dissolved, add more DI water until the desired concentration is reached.
To ensure accurate measurements, it is important to properly calibrate and use the balance. Make sure to tare the balance before each measurement and use a clean and dry container to hold the solid. It is also helpful to measure the solid multiple times and take an average to reduce error.
DI water, or deionized water, is used in lab preparation because it is free from impurities and ions that can affect the outcome of experiments. It also ensures that the concentration of the solution is solely determined by the amount of solid used.
The appropriate flask size for your solution will depend on the amount of solid and DI water needed to reach the desired concentration. It is important to choose a flask that is large enough to hold the solution without overflowing, but not too large as it can affect the accuracy of the measurement.
No, not all solids are suitable for lab preparation. It is important to choose a solid that is soluble in DI water and will not react with the solution. It is also important to consider the purity of the solid and any potential impurities that may affect the experiment.
