Hey /sci/
doing revision and totally forgot how to do titration equations and can't find my notes for it, could you help me with this problem and what formula i need?
A water sample (50mL) was titrated with dilute sodium hydroxide to measure its
acidity, requiring 5.2mL of 0.01M to reach an end point. What is the acidity of the
water expressed in moles per litre, and milliequivalents per litre.

If you are looking for the molarity of the acid in the water it's v1m1=v2m2 but I'm unsure if that is what you want.
>>
Using c1v1=c2v2 you can find the water concentration. Water does autoprolysis and is always in a constant equilibrium between H3O+ and OH-. The acidity, or pH, can found doing -log[H3O+]
That being said, it's a pretty stupid exercise since waters pH is always around 7

underage b&. Do your own homework and kindly fuck off. Thanks.

If you can't model such a basic; system science isn't for you.

Nigga this ain't that hard. The number of moles of NaOH it took you to get to the end point equals the number of moles of H3O+ in water. Do the -log(of that number) and there is your pH
