Investigating Some Factors Which Affect the Rate of Reaction Between Hydrochloric Acid and Sodium Thiosulphate
Background Information
Reactions can be completed at different rates. The rate of reaction is measured by observing how quickly reactants are used up or how quickly products are forming. This can be calculated in three ways:
oPrecipitation - When the products of the reaction is a precipitate, which will cloud the solution. Observing a marker through the solution and timing how long it takes for this marker to disappear will determine the rate of reaction.
oChange in Mass - Re…
