What is the purpose of adding 100 mL of distilled water to a beaker containing metal nitrate solution?
The purpose of adding 100 mL of distilled water to a beaker containing a metal nitrate solution can vary depending on the specific context or experiment. Here are a few possible reasons:
1. Dilution: Adding distilled water to a concentrated metal nitrate solution can be done to dilute the concentration of the solution. This is often necessary when working with solutions that are too concentrated for a specific experiment or analysis.
2. Volume adjustment: The addition of water can be used to adjust the volume of the metal nitrate solution. This is particularly relevant when the final volume needed for an experiment is different from the original volume of the metal nitrate solution.
3. Control variable: In certain cases, adding distilled water to a metal nitrate solution can serve as a control variable in an experiment. By comparing the results obtained with the original solution and the diluted solution, researchers can analyze the influence of the water content on the final outcome.
It's important to note that the specific purpose for adding water to a metal nitrate solution may depend on the particular experiment or procedure being conducted, so it's always advisable to refer to the instructions or experimental design for accurate information.
Adding 100 mL of distilled water to a beaker containing metal nitrate solution serves the purpose of diluting the concentration of the metal nitrate solution. Dilution is the process of reducing the concentration of a solute in a solution by adding more solvent.
To calculate the new concentration of the metal nitrate solution after dilution, you need to know the initial concentration of the solution and the final volume of the diluted solution. Here are the steps to calculate it:
1. Determine the initial concentration of the metal nitrate solution. This can be given in units such as moles per liter (M) or grams per liter (g/L).
2. Measure the initial volume of the metal nitrate solution in the beaker.
3. Add the 100 mL of distilled water to the beaker. Make sure to mix it well to ensure a homogeneous mixture.
4. Measure the final volume of the diluted solution. This will be the sum of the initial volume of the metal nitrate solution and the 100 mL of distilled water.
5. Calculate the new concentration of the metal nitrate solution using the formula:
C1V1 = C2V2
Where C1 is the initial concentration, V1 is the initial volume, C2 is the new concentration, and V2 is the final volume.
Rearrange the formula to solve for C2:
C2 = (C1V1) / V2
Plug in the known values to find the new concentration.
By following these steps, you can determine the purpose of adding 100 mL of distilled water to a beaker containing metal nitrate solution and calculate the resulting concentration of the diluted solution.
