Which of the following is an example of a ‘solid in a liquid’ type of solution?

Explanation

Tincture of iodine contains iodine, normally a solid, dissolved in a liquid alcohol-containing solvent. It is therefore a solid-in-liquid solution in the textbook classification. Vinegar is mainly a liquid-in-liquid aqueous solution, while brass and bronze are solid alloys. Muddy water is a suspension, not a true solution.
