Introduction
Rate of rate of hydrochloric acid and mangesium ribbon
In the reaction between hydrochloric acid and magnesium ribbon, the hydrochloric acid will dissolve the magnesium and produce hydrogen gas.
All chemical reactions involve reactants which when mixed may cause a chemical reaction which will make products.
In my case the reactants are hydrochloric acid and magnesium ribbon. The chemical reaction takes place when the magnesium ribbon is dropped into the hydrochloric acid. The products that are formed during this reaction are hydrogen gas and magnesium chloride. The formula equation for this experiment is:
Mg + 2HCl (r) MgCl2 + H2
Magnesium + Hydrochloric acid (r) Magnesium Chloride + Hydrogen
( s ) ( aq ) ( aq ) ( g )
Magnesium will react with hydrochloric acid, because it is higher in the reactivity series that hydrogen. When the two chemicals react a displacement reaction will take place and the magnesium will displace the hydrogen in the hydrochloric acid forming magnesium chloride and hydrogen gas.
Reactivity Series
K (potassium)
Na (sodium
Li (lithium) all to dangerous to react with a strong acid
Ba (barium)
Ca (Calcium)
..
Mg (magnesium) -
Al (aluminium) manageable metals
Zn (zinc) these metals will react with hydrochloric acid as they
Fe (iron) they are higher in the reactivity series than hydrogen
Sn (tin) and so a displacement reaction will take place
Pb (lead) ¯
..
H (hydrogen)
..
Cu (copper)
Hg (mercury) none of these metals will react with hydrochloric
Ag (silver) acid as they are all lower in the reactivity series than
Al (gold) hydrogen, therefore a displacement reaction will not
happen
Depending on certain factors the rate that this reaction will take place will either increase or decrease...
