Calculate the pH of the solution obtained by mixing 50.0 cm3 of 1 mol dm-3 sodium hydroxide solution with 49.0 cm3 of 1 mol dm-3 hydrochloric acid?
The answer is 1.96 but I’m not sure how you get it?
When you do these types of questions, what do you like out for and how do you tackle them?
When I do these, I either get them right or they go horribly horribly wrong.
Thank you so much!
I might be being stupid, but are you sure you have the concs. around the correct way? At the moment, you have more moles NaOH than HCl which would mean that 1.96 cannot be correct.

I haven't changed anything about the question, just copied and pasted it straight from a past paper.
I think you use Kw to figure out what the concentration of the hydrogen ions would be?

No I think the exact same thing the pH should be a lot higher surely
EDIT: The question that I'm stumped with it is the first one and it's a multiple choice. But in my textbook, it's not given out as a multiple choice question but a normal one. Very weird.
