Final answer:
The solubility of potassium iodide (KI) in water at 10°C cannot be determined with the given information; a solubility chart or table specific to KI and that temperature would typically be consulted to find the exact value.
Step-by-step explanation:
The solubility of potassium iodide (KI) in water at 10°C is not explicitly given within the provided information. However, solubility generally refers to the maximum amount of a substance that can dissolve in a particular solvent at a given temperature. While the solubility of lead (II) iodide and other substances such as silver chloride and potassium hydroxide are discussed, the information required to directly answer the question about potassium iodide's solubility at 10°C is missing.
To determine the solubility of potassium iodide at 10°C, one would typically refer to a solubility chart or table specific to that substance and temperature. In general, the solubility of ionic compounds like potassium iodide is usually higher than that of lead (II) iodide or silver chloride because KI is a strong electrolyte and highly soluble in water.
