Simple acid-base question!! (1 Viewer)

What volume of 0.250 mol/L sodium hydroxide would be required to completely react with 25.0 mL of a solution of citric acid that has pH = 2? (3 marks)

Just from a past school trial, my answer didn't match up with the solutions, not sure why.

Any help would be appreciated,
Thanks

This is what they've said, but I'm not sure I agree with the concentration of the citric acid... a bit confusing
What's your working look like?

my concentration of citric is 1/300 is that the value of conc3entration th picture doesnt open

Yeah, that's what i got too
(10^-2)/3
I think the solution must be wrong... it has it at 0.14mol/L

Cheers
