This question asks us to consider separate aqueous solutions of hcl and h2s .o4 with the same molar concentrations.
00:11
Then it says you wish to neutralize an aqueous solution of n -a -o -h sodiumlydroxide.
00:17
Then the question says, for which acid solution would you need to add more volume in milliliters to neutralize the base? a, the hcl solution, b, h2s -o -4 solution, c, you need to know the concentrations to answer the question, d, you need to know the volume and concentration of the n -a -o -h solution to answer the question, or e, c, and d, and then it wants us to explain.
00:44
So this is pretty straightforward.
00:47
When you want to neutralize a base, you want to neutralize this oh group that is oh -h -minus in solution, and you do that with protons, or h -plus.
00:56
Ions.
00:58
And in hcl, you get one, so i'm going to write, you get one h plus ion.

And from h2s...
