Question

Which of the following has the strongest base? CH₃COO (with Kb = 5.6 * 10¹0).

a) CH₃COO with Kb = 5.6 * 10¹0

b) NH₃ with Kb = 4.8 * 10¹0

c) HCO₃⁻ with Kb = 6.2 * 10⁹

d) OH⁻ with Kb = 1.2 * 10¹1

Answer 1

OH⁻ with a Kb value of 1.2 × 10¹ⁱ is the strongest base among the given options, as the strength of a base is directly related to the magnitude of its Kb value.

Step-by-step explanation:

To determine which of the given compounds has the strongest base, we look at the Kb values (base ionization constants). The compound with the highest Kb value will be the strongest base because it is more effective at accepting protons (H+ ions).

• CH₃COO with Kb = 5.6 × 10¹⁰
• NH₃ with Kb = 4.8 × 10¹⁰
• HCO₃⁻ with Kb = 6.2 × 10⁹
• OH⁻ with Kb = 1.2 × 10¹ⁱ

Comparing these values, OH⁻ has the largest Kb value, which is 1.2 × 10¹ⁱ, indicating it is the strongest base among the options given.
