I want to find out if as the concentration of sodium thiosulphate decreases the rate of reaction i.e. the rate of reaction is directly proportional to the concentration of the sodium thiosulphate. BACKGROUND KNOWLEDGE What Scientific Knowledge Do You Have Which Might Be Useful In Planning Your Investigation? We have scientific knowledge from preliminary experiment of hydrochloric acid and sodium thiosulphate. Na S 0 + 2HCL 2NaCl + H O + SO + S ² ² ³ (aq) (aq) (aq) ² (¹) ² (aq) (s) When 10cm³ of 1M HCL was added to 50cm³ of Na S O (40g/dm³) after about 60 ² ² ³ seconds the sodium thiosulpahte clouded over and prevented us from seeing the x placed on a piece of paper beneath the conical flask. The reaction was exothermic...
