Sodium Thiosulphate reacts with hydrochloric acid forming sulphur, water, sodium chloride and sulphur dioxide. Dilute Hydrochloric acid is added to Sodium thiosulphate. Inhalation: sodium thiosulphate can cause upper respiratory tract and mucous membrane irritation. Hydrochloric acid solution is corrosive to eyes and skin. The rate of reaction between sodium thiosulfate and dilute hydrochloric acid can be measured by the time it takes for the sulfur precipitate to be formed, as shown in the equation below: 2HCl(aq) + Na 2 S 2 O 3 (aq) 2NaCl(aq) + SO 2 (aq) + S(s) + H 2 O(l) Hydrochloric Acid + Sodium Thiosulfate Sodium Chloride + Sulfur Dioxide + Sulfur + Water sodium thiosulfate + hydrochloric acid → sodium chloride + water + sulfur dioxide + sulfur. When reacted with dilute hydrochloric acid, sodium thiosulphate gives sulphur dioxide, water, and sulphur as the product. Sodium thiosulphate reacts with Hydrochloric acid reacts to form yellow precipitate of sulphur. When Hydrochloric acid is added to a solution of sodium thiosulphate, a reaction takes place in which sulphur is slowly precipitated and the mixture becomes more and more opaque. As a group in class we decided to change the concentration. I need to know what precipitate is formed that makes the solution cloudy, which makes the cross disappear. Pb(NO 3) 2 + 2HCl → PbCl 2 + 2HNO 3. Reaction of Sodium Thiosulphate with Hydrochloric acid Safety: Good laboratory practice should be followed. What precipitate is formed between the reaction of sodium thiosulfate and hydrochloric acid? In this experiment there are two solutions used, Sodium Thiosulphate and Hydrochloric Acid. Investigating the rate of reaction between sodium thiosulphate and hydrochloric acid Background Sodium thiosulphate and hydrochloric acid react to produce sulphur. When dil. Sulphur dioxide (SO 2) and water (H 2 O) are also formed, but it is the solid sulphur that has the biggest impact here. 2HCl (aq) + Na 2 S 2 O 3(aq) 2NaCl (aq) + SO 2(g) + S (s) + H 2 O (l). The rate of this reaction can be measured by looking at the rate at which the product solid sulfur (S (s)) is formed. The reaction used is that between a sodium thiosulfate solution and hydrochloric acid: 2HCl (aq) + Na 2S 2O 3(aq) → 2NaCl (aq) + SO 2(aq) + S (s)↓ + H 2O (l) The precipitate of sulfur formed gradually obscures a cross marked on paper and placed beneath the reaction flask.
