question 51

Multiple Choice

Which of the following chemical equations corresponds to the base ionization constant,K_b,for hydrogen sulfite ion (HSO₃^-) ?

• A) HSO₃^-(aq)+ H₂SO₃(aq) \( \rightleftharpoons \) 2 H₂SO₃(aq)
• B) HSO₃^-(aq)+ H₂O(l) \( \rightleftharpoons \)SO₃^2-(aq)+ H₃O⁺(aq)
• C) HSO₃^-(aq)+ OH^-(aq) \( \rightleftharpoons \)SO₃^2-(aq)+ H₂O(l)
• D) HSO₃^-(aq)+ H₃O⁺(aq) ? H₂SO₃(aq)+ H₂O(l)
• E) HSO₃^-(aq)+ H₂O(l) ? H₂SO₃(aq)+ OH^-(aq)

Definitions:

Enable

To make a device or system operational; to allow a process or function to proceed.

Permanent Contact

A type of electrical contact that remains closed to ensure a constant flow of electricity, typically used in switches or relays.

Normally Open

A term describing an electrical switch or relay contact that is open (not conducting) when in its default state, closing only in response to a control action.

Normally Closed

A term used to describe a switch or circuit condition where the default state is closed, allowing current to flow unless actuated to open.
