it is very easy to prepare working solution from a stock solution we use the formula for this purpose which is: C1V1 = C2V2 C1 is the concentration of the stock solution V1 required volume from the stock solution C2 concentration of the working solution V2 volume of the working solution


What is as stock solution?

A stock solution is a highly concentrated solution that is usually diluted in labs to get more precise moralities in experiments.


Preparation of 100ml 0.5N from a stoke solution of 5.0N HCL?

To prepare 100ml of 0.5N HCl solution from a stock solution of 5.0N HCl, you need to dilute the stock solution with water. To calculate the volume of stock solution needed, you can use the formula C1V1 = C2V2, where C1 is the concentration of the stock solution, V1 is the volume of the stock solution needed, C2 is the desired concentration, and V2 is the final volume of the diluted solution. So, V1 = (C2 * V2) / C1 = (0.5 * 100) / 5 = 10ml of the stock solution. Dilute this 10ml of stock solution to 100ml with water.


How do you make a 5 X solution from 10 X stock?

To make a 5X solution from a 10X stock, you can dilute the 10X stock solution by adding an equal volume of diluent (such as water or buffer) to the original solution. For example, if you have 1 mL of the 10X stock solution, you would add 1 mL of diluent to make a 5X solution.


How can you effectively dilute a stock solution?

To effectively dilute a stock solution, you can add a specific volume of solvent (such as water) to the stock solution to decrease its concentration. The formula for dilution is C1V1 C2V2, where C1 is the initial concentration of the stock solution, V1 is the volume of the stock solution, C2 is the final desired concentration, and V2 is the final volume after dilution. By following this formula and measuring the volumes accurately, you can dilute the stock solution to the desired concentration.


Is stock is a solution?

Generally, yes.


How do you prepare 10 mm solution with 4 m stock solution?

To prepare a 10 mm solution, you would dilute the 4 M stock solution. Use the formula C1V1 = C2V2, where C1 is the concentration of the stock solution (4 M), V1 is the volume of stock solution needed, C2 is the desired final concentration (10 mM), and V2 is the final volume of the solution. Calculate the volume of stock solution needed to achieve the desired concentration, then add solvent (usually water) to reach the final volume.


Why is it important not to pipette a reagent solution directly from bottle of a reagent stock solution?

Pipetting directly from a reagent stock solution can lead to contamination of the stock solution. By introducing potential contaminants back into the stock solution, it can lead to inaccurate results in future experiments and compromise the integrity of the stock solution for other experiments. It's best practice to use a separate vessel to aliquot the required amount of reagent before transferring to the experiment.


What is difference between stock and working solution?

A stock solution is a concentrated solution of a substance that is diluted to make working solutions of desired concentrations. A working solution is a solution ready for immediate use in an experiment or process. Stock solutions are typically stored for longer periods and used to prepare multiple working solutions.
