Question

50 ML of 0.001 M phosphoric acid are exactly neutralized by the addition of 0.005 N Naoh the molarity of resulting salt is?

Answer 1

@Kryten help

Answer 2

i think we have to find milli eq

Answer 3

H3po4 +3Naoh gives na3po4 + 3h20

Answer 4

here is the equation now plzz help me....

Answer 5

@Kryten

Answer 6

ok now calculate moles of each reactants from concentration and then put their moles in ratio relationship from which you can calculate moles of product salt and its molarity

Answer 7

hm..........hm............ @Kryten u changed a lot during these days earlier u was not like this u used to help me(shameer1) by attaching a file i was in a dream that why people like u take that much risk to help me but now i dont know wat is keeping this away from u................any how thanzzz a billion for helping me(shameer1) a lot earlier but at the same time i am also sad that now u are nt.................. drops !!!!

Answer 17

i told you steps! read what i wrote and do so on paper!

Answer 18

ok after calculating the moles.....next step i didnt understand

Answer 19

c= n/V
n= cV -> H3PO4
n(H3PO4):n(NaOH)=????
n(NaOH) = ???? * n(H3PO4)
V=n/c ->NaOH
n(Na3PO4) = ??? n(H3PO4)....

Answer 20

and thats all from me, im going out...
