Hi

I did an titration of decarbonised coke containing solely phosphoric acid with 0.0075M of NaOH. After plotting the graph, i got a first equvalence pt of 3.4ml of NaOH added and that is at the pH of 6. Now i am supposed to find out the theoretical pH of at the equivalence pt .. i had been trying for days n still cant get anything close...

PLz Help
