Strong and Weak Acids have Different Reaction Rates

Magnesium will react with an acid and make hydrogen gas. The more concentrated the acid, the faster the magnesium will react and you will see bubbles of hydrogen being produced more quickly.

A strong acid and a weak acid of the same concentration will react at different rates with the same metal.

Limiting Reactants – A Worked Example

Zinc reacts with dilute hydrochloric acid according to the equation:

Zn (s) + 2HCl (aq)      ->       ZnCl₂ (aq) + H₂ (g)

If 0.05 mole of zinc was added to 0.075 mole of hydrochloric acid,

(a)        identify the limiting reactant;

(b)       calculate the amount (in moles) of the excess reactant which remained unreacted;

(b)       calculate the amount (in moles) of zinc chloride formed.

Solution :
