Answer to Question #132230 in General Chemistry for Victor Benjamin

Question

Y is a solution containing 6.30gdm-3 of HNO3
Z is a solution of hydrated sodium trioxocarbonate (iv) (NaCo3 XHH2O) containing 8.10gdm–³ of hydrated.
(a) Pippette 25cm³ of solution Z into a conical flask and add 2 drops of methyl orange indicator.
(i) Titrate solution Y against Z and record the burette reading. Repeat the experiment at least twice with fresh portions of Z and tabulate your readings. Calculate the average volume of Y used.
(ii) Write a balanced equation for the reaction.
(b) Determine:
(i) the concentration of Y in moldm–³
(ii) the moles of Y in the average titre
(iii) Number of mole Z consumed
(iv) concentration of Z in moldm–³
(v) the number of water molecules in one mole of NaCo3 XH2O
