Factors that affect how the PH changes during a titration experiment
Factors that affect how the PH changes during a titration experiment.
Concentration of the alkali
Having a higher concentration of alkali will mean that there will be more molecules closer together for the acid to collide with. This will speed up the reaction as collision theory suggests that molecules have to collide to react and if there are more molecules to collide with the reaction will happen faster as there is a higher chance of a collision.
Volume of alkali
An increase in volume would mean that the neutralisation would take longer as you would need an equal amount of the same strength acid in order to neutralise it. Furthermore in collision theory if there is a bigger space that the molecules are in then the molecules are less likely to collide which means that the reaction would be slowed.
Concentration of the acid
Having a higher concentration of acid would like having a higher concentration of the alkali would speed up the reaction. This is because collision theory states that if there are more molecules in a set area there is a higher chance of the molecules colliding with each other which would speed up the reaction.
Volume of the acid
An increase in the volume of the acid would mean that the reaction would be slowed. This is because you need the same amount of acid and alkali to reach PH 7 or neutral. This is because it would be the same amount just in a larger space reducing collisions.
Temperature
A higher temperature would mean that the molecules would have more energy this means that when they collide they would collide with enough force to start a reaction off. This speeds up the reaction as the molecules always create the reaction rather than glancing off of each other and not starting a reaction.
Presence of a catalyst
A catalyst holds one reactant in place so that another can collide with it directly and not glance off of it. This speeds up the reaction as more direct collisions take place. An example of a catalyst is Cobalt in the
