You have a stock solution of hydrochloric acid ... - SS1 Chemistry Solutions and Concentration Question
You have a stock solution of hydrochloric acid (HCl) with a concentration of 10 M. How would you prepare 500 mL of a 2 M HCl solution through dilution?
To calculate the volume of the stock solution needed, we can use the dilution equation:
C1V1 = C2V2
Where:
C1 = initial concentration (10 M)
V1 = initial volume (unknown)
C2 = final concentration (2 M)
V2 = final volume (500 mL)
Rearranging the equation, we have:
V1 = (C2V2) / C1
V1 = (2 M x 500 mL) / 10 M
V1 = 100 mL
Therefore, you would measure 100 mL of the 10 M HCl stock solution and then add enough solvent (typically water) to make the total volume 500 mL.
