Question

Hi I am doing a titration lab do calculate the concentration of HCl.
I know the formula is c=n/V
But which one is V in the following:
I add 20 ml HCl and 10 ml water in the cup I will use to titrate with. Which is the V? Is it 20 ml or the total 30 ml?

Answer 1

Answer:

30ml

Explanation:

V refers to the total volume.

Therefore, V = vol(HCL) + vol(H20)

c = number of given moles of hcl  /  volume of hcl present
