What Happens When Hydrochloric Acid and Sodium Thiosulphate React?

When hydrochloric acid (HCl) and sodium thiosulphate (Na2S2O3) are combined, an interesting reaction takes place and the colourless solution turns opaque. But why does this happen, and how can we use this opacity to determine the rate of reaction? The Reactants The chemicals used in this experiment are both extremely important in their own areas. In case you missed our previous [...]
