Marks are in sequential order, i -> 1 mark, ii -> 1 mark ,etc..
I believe i) is simply HCl + NaOH --> NaCl + H2O
Other than that, the rest are correct - just cut back on the number of significant figures :).
I think we'll get a good calculation question this year.
Try this one:
The solubility of highly soluble, thermally unstable salts such as ammonium chloride may be determined by back titration.
In one experiment a 5.00 mL saturated solution of ammonium chloride, NH4Cl, at 20oC,
was...
