Red
Benedict's solution is a deep blue color. When mixed with milk or any kind of reducing sugar, the solution will change color to yellow, orange, red, or brown depending on the amount of reducing sugar present in the milk.
Petrol changes color when mixed with iodine solution due to covalent bonding.
Benedict's solution turns brick red when mixed with simple sugars like glucose, fructose, or maltose. This color change indicates the presence of reducing sugars in the solution due to the reduction of copper ions in the Benedict's solution.
orange
Nothing it is colourless solution.
When iodine solution is mixed with starch solution they produce blue-black color.
The color remain red because vinegar is an acidic solution.
grey
Bougainvillea juice will turn from its original color to pink when mixed with dove solution, due to the presence of anthocyanin pigments in the bougainvillea juice reacting with the alkaline nature of the dove solution.
deep green
When copper chloride solution is mixed with aluminum, a redox reaction occurs where the aluminum reduces the copper ions to form copper metal. This results in a color change from blue-green (copper chloride solution) to colorless (copper metal precipitate), giving the appearance of fading in color due to the formation of a solid copper instead of a colored solution.
when congo red was mixed with milk it produced pink color solution.
