Question

9. Gaseous hydrobromic acid reacts with fluorine to produce gaseous hydrofiuoric acid and Bhioi i SO.O of hydrobromic acid and 39.OL of fluorine are used in the reaction, calculate the theoretical yield of hydrofluoric acid in iters Assume the reaction occurs at STe 22. L/mel1m

Answer 1

H2A (aq) + NaOH(aq) -------------> NaHA (aq) + H2O

1 mole of NaOH react with 1 mole of H2A

1.34*10^-3 moles of NaOH react with 1.34*10^-3 moles of H2A

molar mass of diprotic acid   = mass of acid/no of moles of acid

                                                 = 0.18/1.34*10^-3    = 134.3g/mole

molar mass malic acid (C4H6O5)     = 134.3g/mole

malic acid ( C4H6O5) >>>>>>answer
