有冇人知個procedures點寫?
--------------------------------------------------------------------------------
張紙上面既 introduction係話: in this technique, the sodium chlorate(I) is allowed to react with an excess of potassium solution in the presence of acid, liberating iodine, which is then titrated against standard sodium thiosulphate solution.

Procedures: work out your own detail procedure yourselves
Note. 1 carry out 4 titrations altogether to yield three consistent results.
          2 when the reaction mixture becomes pale yellow, add a drop of starch indicator and carry on titration to the end-point

咁其實我暇想知係個sodium chlorate(I) 同potassium solution 洗唔洗稀釋既呢?
