Aim- To investigate a factor which affects the rate of reaction in the reaction between sodium thiosulphate and dilute hydrochloric acid. When sodium thiosulphate and hydrochloric acid react they produce a cloudy Solution. The two chemicals are both clear solutions and will react together to form a yellow precipitate of sulphur. As the solution will turn cloudy, we can observe the rate of reaction by placing a black cross underneath the beaker and seeing how long it takes for it to disappear by timing it. The reaction happens because of the collision theory. Every atom vibrates and depending on the circumstances the strength of the vibrations might increase or decrease. When two substances are placed together, they will vibrate and often collide. When the two atoms collide a certain amount of energy is needed for the reaction to take place. The minimum amount of energy that is needed for a reaction to take...
