Copper Chloride is a light brown colour in its anhydrous (dry) state and if allowed to absorb moisture from the atmosphere turns to a bluey-green coloured dihydrate.
The color of the paper changes based on the acidity or alkalinity of the solution it is dipped in. By comparing the color of the paper to a pH color chart, the pH of the solution can be determined.
The solution color of cupric oxide is blue to green.
This solution, if it is pure, is white or colorless.
The solution of CuSO4 is blue.The solution of FeSO4 is green.
The pH 10 solution will turn purple because the purple color is stable over a wide pH range. However, if the purple solution contains an indicator that changes color at different pH values, it may undergo a color change.
Lugol's solution is a solution of iodine (1-5%) and potassium iodide in water. So the solution should have the pale color of iodine and the color should be pale (light) brown.
The color of iron (III) chloride solution is brown.
Any color is possible.
The color of the paper changes based on the acidity or alkalinity of the solution it is dipped in. By comparing the color of the paper to a pH color chart, the pH of the solution can be determined.
Colorless
2 percent bromine solution typically has a reddish-brown color.
A solution can still contain color, but also be clear. Take a pool for example, the water is slightly blue but you can still see through it. A colorless solution is when there is no color, like water in a store bought water bottle.
A nickel sulfate solution is typically blue-green in color. The exact hue can vary depending on the concentration of the solution.
white color solid and colorless solution
Iron III sulfate solution is typically pale yellow in color.
A cobalt sulfate solution is typically blue in color.
The solution color of cupric oxide is blue to green.
