(C) Magnesium with Acid
Magnesium reacts vigorously with acid leaving a solution of magnesium sulphate and hydrogen below is the word equation.
Mg + H2So4 MgSo4 + H2
How is acid rain formed? ... After they have been released they react with the gases in the air and with the rain-water. Reactions like this make rain water acidic. Acid rain has a ph of between 5 and 2 the equation for acid rain is
H2O + SO2 H2SO3
Some factors affecting the reaction rate are as follows,
TEMPERATURE
At higher temperatures particles are moving faster so there are more collisions. ... The increased concentration of acid rain brings the particles together so this will increase the chance they have of colliding which will in turn speed up the reaction rate. ... This will create harmful gases like sulphur dioxide which will increase the concentration of acid rain. ...
Variables
The variable I will change is the concentration of the acid.
The variables I will keep the same is temperarture, surface area of magnesium, mass of magnesium and volume of acid. ... I will use a measuring cylinder to keep the volume the same (50cm3)
The variable I am going to measure is the time it takes the magnesium to react with the acid.
