The Lewis acid-base theory is broader than Brønsted-Lowry because it defines:
AAcid as H⁺ donor; base as H⁺ acceptor
BAcid as an electron pair ACCEPTOR; base as an electron pair DONOR
CAcid as an OH⁻ producer; base as H⁺ producer
DAcid as any cation; base as any anion
Question 2
The Henderson-Hasselbalch equation pH = pKa + log([A⁻]/[HA]) is used to calculate:
AThe pH of a strong acid solution
BThe pH of buffer solutions and to determine the
CThe exact concentration of H⁺ in any solution
DThe melting point of a salt
Question 3
The solubility product (Ksp) of AgCl at 25°C is 1.8 × 10⁻¹⁰. The solubility of AgCl in pure water is:
A1.8 × 10⁻¹⁰ mol/L
B1.34 × 10⁻⁵ mol/L
C9.0 × 10⁻¹¹ mol/L
D3.6 × 10⁻¹⁰ mol/L
