What is the color a mixture of sodium and potassium compounds (use the cobalt glass)??
A mixture of Na and K give a yellow color in the flame. The Na yellow flame completely blocks the violet from K. Using a Cobalt glass filters the yellow out and leaves a reddish color for K. Did you not see this when you did the experiment?
yes , i did . but i don't sure . thank you
A mixture of sodium and potassium compounds typically appears as a pale yellow color. However, in order to observe the color of this mixture more accurately, a cobalt glass can be used. Cobalt glass is a dark blue glass that filters out certain wavelengths of light, allowing us to see specific colors more clearly.
To observe the color of the mixture using cobalt glass, follow these steps:
1. Obtain a small amount of the mixture of sodium and potassium compounds.
2. Hold the cobalt glass up to your eye or place it in front of a light source.
3. Look at the mixture through the cobalt glass.
4. The color of the mixture will now be altered due to the filtering effect of the cobalt glass.
5. Observe the color and note any changes in comparison to the color observed without the cobalt glass.
It is important to note that the actual color observed may vary depending on the specific compounds present in the mixture and their concentrations. Additionally, the intensity of the color may also vary based on lighting conditions and the transparency of the glass.
