What chemical compounds are yellow when dissolved in water?
Some chemical compounds that are yellow when dissolved in water include potassium chromate (K2CrO4), potassium dichromate (K2Cr2O7), and picric acid (C6H3N3O7). These compounds exhibit yellow color due to their specific molecular structures and interactions with water molecules.
Why is sand yellow in colour?
