Question about potassium ferrocyanide solution. Thanks

No, exposing potassium ferrocyanide solution to strong sunlight for 5 hours in summer will not cause it to decompose into potassium cyanide. Potassium ferrocyanide is a stable compound and is not easily decomposed by sunlight. In the case of potassium ferrocyanide (K4Fe(CN)6), it is a stable compound that does not undergo spontaneous decomposition when exposed to strong sunlight. The structure of potassium ferrocyanide is highly resistant to photochemical reactions caused by light energy. Therefore, it does not undergo a transformation into potassium cyanide (KCN) simply by exposure to sunlight. Chemical reactions typically require specific conditions, such as the presence of catalysts or the application of specific energy sources, to facilitate decomposition.
