Metal's Reaction with Acid
Aim-to discover how much gas is produced when a metal is reacted in
acid.
Apparatus-to follow through the experiment I will use the following
apparatus:
Sulphuric acid
Magnesium ribbon
Ice cream tub
Delivery tube with bung
250ml measuring cylinder for gas collection
Conical flask
A very small beaker
A weighing machine
25ml measuring cylinder for acid
Cling-film
Method- below is the method I will use:
· Firstly I will weigh the magnesium for the correct amount, and
measure out the amount of sulphuric acid I wish to use.
· I will place a measuring cylinder filled with water upside down in a
tub also filled with water, and finally I will secure it will a clamp.
Before placing the measuring cylinder under the water I will ensure
that no bubbles of air enter it by covering the opening with
cling-film.
· Here is diagram of my equipment with my chosen amount of magnesium
ribbon kept out of the sulphuric acid in a little beaker.

· Then I will lower the beaker with the magnesium into the acid.
· When the correct amount of magnesium is inside the acid and the lid
is securely fastened, so that no hydrogen can escape, I will begin to
shake the container to make the reaction take place more quickly. It
is important to make sure the measuring cylinder doesn't squash the
delivery tube, because this would cause a build up of compressed gas,
which is very dangerous.
· When I have collected my results I will place them in a table like
the one used below for my preliminary experiment. I will also plot
them on a graph so I can see more clearly any anomalous results and
see whether it appears as I have predicted.
Variables- what I will keep constant to ensure a fair test, what I
will measure, and what will vary as the measurement changes:

The data we gathered from our analysis are presented in a formal way on the following page.

Reaction Between Hydrochloric Acid and Magnesium Introduction In the reaction between hydrochloric acid and magnesium. Hydrochloric acid will dissolve the magnesium and produce hydrogen. gas. The sand is All chemical reactions involve reactants which when mixed may cause a chemical reactions which will make products. In my case, the reactants are hydrochloric acid and magnesium ribbon.

The Effect of Concentration of Hydrochloric Acid on the Rate of Reaction with Magnesium Aim: To investigate the effect of concentration of hydrochloric acid on the rate of reaction with magnesium Prediction: As the concentration of the hydrochloric acid increases, so will the rate of reaction Hypothesis: In a reaction, particles of two different reactants react together to form a product. The reaction only takes place on account of two things, if the particles collide, and if the collision has enough 'activation energy'. The two reactant particles, in this case magnesium particles and hydrochloric acid particles, must collide with each other on the correct 'collision course'. If this does not occur then no chemical reaction will take place. The reaction must also have enough energy, this can be affected by temperature, the more heat the particles have the faster they move and so the more energy therefore more chance of successful collisions.
