Question

a 6.0 m base produces 0.25 m oh⁻ in solution. is this a strong or a weak base? weak base! the concentration of oh⁻ is significantly less than the concentration of the base. strong base! the base produces oh⁻ in solution. its not possible to determine this without the chemical formula of the base. weak base! the majority of the base reacts with water to produce oh⁻ ions.

Explanation:

A strong base completely dissociates in solution to produce hydroxide ions. Here, a 6.0 M base only produces 0.25 M of $OH^-$ ions, indicating incomplete dissociation. Incomplete dissociation is characteristic of weak bases.

Answer:

Weak base! The concentration of $OH^-$ is significantly less than the concentration of the base.
