Describe in detail how you would prepare 1000 ml of 0.1 M NaOH from 6 M of NaOH stock solution.
mL1 x M1 = mL2 x M2
1000 x 0.1 = mL2 x 6
Place mL2 in a 1 L volumetric flask, and add water to the mark of the flask, mix thoroughly, stopper.
Describe the procedure for preperation 100 ml of a 0.10 M NaOH solution from 1.0 NaOH show all the steps of calculation
To prepare 1000 ml of 0.1 M NaOH from a 6 M NaOH stock solution, you will need to use the equation:
(C1)(V1) = (C2)(V2)
Where:
C1 = initial concentration of the stock solution (6 M)
V1 = volume of the stock solution used (unknown)
C2 = final concentration of the desired solution (0.1 M)
V2 = final volume of the desired solution (1000 ml)
Step 1: Determine the volume of the stock solution needed (V1):
Using the equation above, rearrange it to solve for V1:
V1 = (C2 * V2) / C1
Substituting the values:
V1 = (0.1 M * 1000 ml) / 6 M
V1 = 16.67 ml
So, you will need 16.67 ml of the 6 M NaOH stock solution.
Step 2: Calculate the volume of distilled water needed:
To reach the final volume of 1000 ml, subtract the volume of the stock solution (V1) from it:
Volume of distilled water needed = 1000 ml - 16.67 ml = 983.33 ml
Therefore, you will need to add approximately 983.33 ml of distilled water to the 16.67 ml of the 6 M NaOH stock solution to make 1000 ml of 0.1 M NaOH solution.
While preparing the solution, it is crucial to handle concentrated solutions with caution, wear appropriate protective gear such as gloves and goggles, and work in a well-ventilated area.
