How do you dilute solutions? Say you have 10mL of water, .1 M HCl, and you want to make it into .08,.06...How?

Answer 1

Dilution formula: C1 x V1 = C2 x V2

As long as both concentrations (C) are the same unit and the volumes (V) are the same unit you can use that formula for any dilution.

ex. How many mL' s of 0.1M HCl are need to make 10mL of 0.08M?

C1= 0.1 V1 = x C2= 0.08 V2 = 10 mL

0.1x = (10)(0.08)
x = 0.8 mL

So, you would use 0.8 mL of the 0.1M HCl and add 9.2 mL of water to make 10 mL's of 0.08 M.
