Sample Questions

Question 1
In the Brønsted–Lowry model used in the French Terminale programme, an acid is best defined as a species that:
donates a hydrogen ion (H+) during a reaction
accepts a hydrogen ion (H+) during a reaction
accepts a pair of electrons
increases the OH- concentration of a solution
Question 2
A solution has a hydronium-ion concentration [H3O+] = 1.0 x 10^-3 mol/L at 25 °C. What is its pH?
3.0
11.0
0.001
-3.0
Question 3
The acid dissociation constant of a couple AH/A- is written Ka. The relationship linking pH and pKa for that couple in solution is the Henderson–Hasselbalch-type relation:
pH = pKa + log([A-]/[AH])
pH = pKa - log([A-]/[AH])
pH = pKa + log([AH]/[A-])
pH = -pKa + log([A-]/[AH])
Question 4
On a predominance diagram for the couple CH3COOH/CH3COO- (pKa = 4.8), for which pH does the basic form CH3COO- predominate?
pH > 4.8
pH < 4.8
pH = 4.8 only
pH < 0
Question 5
During an acid–base titration monitored by pH-metry, the equivalence point is defined as the point at which:
the reactants have been introduced in stoichiometric proportions
the pH of the mixture is exactly 7
the indicator first changes colour permanently
the conductivity reaches its maximum value
