I'm PhD research scholar, I prepared SnO sample of color black and kept my sample in desiccator some days back. But now it is converted into light yellow color. what might be the reason? any idea?
The color of a sample can change due to various factors such as chemical reactions, exposure to light, temperature changes, and physical changes.
The color change in a sample is caused by the absorption and reflection of specific wavelengths of light by the molecules present in the sample. This can be due to changes in the molecular structure or composition of the sample.
In some cases, the color change in a sample can be reversed by reversing the factors that caused it, such as removing the cause of a chemical reaction or changing the temperature or light exposure. However, in some cases, the color change may be permanent.
The color change in a sample can be measured using various methods, such as colorimeters, spectrophotometers, or visual comparison with a color scale. These instruments measure the amount of light absorbed or reflected by the sample at specific wavelengths.
Understanding the color change in samples has various applications in fields such as chemistry, biology, materials science, and quality control. It can help identify substances, monitor chemical reactions, and determine the quality and purity of products.
