Question 1
In the Brønsted–Lowry model used in the French Terminale programme, an acid is best defined as a species that:
Correct Answer:
donates a hydrogen ion (H+) during a reaction
Question 2
A solution has a hydronium-ion concentration [H3O+] = 1.0 x 10^-3 mol/L at 25 °C. What is its pH?
Correct Answer:
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:
Correct Answer:
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?
Correct Answer:
pH > 4.8
Question 5
During an acid–base titration monitored by pH-metry, the equivalence point is defined as the point at which:
Correct Answer:
the reactants have been introduced in stoichiometric proportions
