Freon 113 is a solvent that has been used to produce which of the following?

Freon 113 is a solvent that has historically been used in the development of latent prints using ninhydrin, which reacts with amino acids present in the sweat and residue left by fingers. When ninhydrin is applied to porous surfaces, it creates a purple-blue compound known as Ruhemann's purple, which allows for visualization of the fingerprints.

Ninhydrin is especially effective for developing prints from paper, fabrics, and other porous materials and is preferred in forensic analysis for its reliability and ease of use. The use of Freon 113 helps to dissolve ninhydrin to facilitate its application on surfaces, enhancing the development process for latent prints.

In contrast, superglue, iodine, and magnetic fingerprints do not involve Freon 113 directly. Superglue fuming is a different method that relies on cyanoacrylate, while iodine relies on sublimation for print visualization. Magnetic fingerprinting typically refers to the use of magnetic powders for developing prints, which does not relate to solvent use. Therefore, the association of Freon 113 with ninhydrin for latent print development is what makes this answer correct.
