Homework Statement
how would you make a 5pH solution from citric acid(1L)
Homework Equations
pH= log(H+)
The Attempt at a Solution
So I will try to work backwards from the [H+]
antilog(-5) = 10^-5 M H+ needed
this number can be divided by 3, because citric acid is triprotic
3.33*10^-6 moles * 210.14 g/mol = 7*10^-4 g brought to volume with 1 liter
