What affects the rate of reaction between
Sodium thiosulphate and Hydrochloric acid?
Prediction
I predict that the more concentrated the acid the faster the rate of reaction.
Theory to back up my prediction
Particle theory tells us that the more particles the more frequent successful collisions there will be. When the concentration of the acid is increased the rate of reaction increases because of more successful collisions.
Low concentrated acid High concentrated acid
Variables:
Catalyst
Concentration
Temperature
Plan
In this experiment I am going to investigate what affects the rate of reaction between sodium thiosulphate and hydrochloric acid.
A chemical reaction can only happen if the molecules frequently and successfully collide into each other. These molecules have to hit each other in the right direction and at the right speed and with the right amount of energy.
