Which of the following occurs as a result of a weak fixer solution?

A weak fixer solution can lead to a milky appearance on the film due to improper fixation. When the fixer's chemical composition is insufficient or diluted, it fails to adequately remove unexposed silver halide crystals from the film emulsion. These remaining crystals can cause the film to appear foggy or milky because they scatter light instead of allowing for a clear image.

In high-quality radiographic imaging, proper fixation is crucial for achieving a clear and high-contrast image. If the fixer is not strong enough or properly maintained, the developing process can result in poor image quality, like cloudiness, which impacts the film's diagnostic value.
