Question

You are making a 1M working solution of HCl, and you have a 10M stock available. How do you achieve the desired concentration?

a) Dilute with more HCl
b) Dilute with water
c) Concentrate the solution
d) Mix with another acid

Answer 1

To achieve a 1M working solution of HCl from a 10M stock solution, you need to dilute it with water.

Step-by-step explanation:

To achieve a 1M working solution of HCl from a 10M stock solution, you need to dilute it with water. Dilution is the process of adding more solvent (in this case, water) to reduce the concentration of the solute (HCl). By diluting the stock solution with water, you will decrease the concentration of HCl and achieve the desired 1M concentration.
