Question
Write a balanced symbol equation for the neutralisation reaction between hydrochloric acid and sodium hydroxide.
Answer
HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l)
Explanation
The question tests the student’s ability to apply the definition of a neutralisation reaction and to balance the equation using the given formulae. It requires recall of the reactants and products and application of stoichiometric balancing.
Common mistake
Common Mistake in Writing Balanced Equations
Students often forget to balance the number of atoms of each element on both sides of the equation when writing balanced symbol equations for neutralisation reactions.
To fix this, carefully count the number of atoms of each element in the reactants and products, and adjust the coefficients to ensure they are equal on both sides.
