Question-Flame Lab
We had to do this lab where we tested different salts to see what color they gave off when we held them to fire.
There were 9 questions we had to answer and I am kinda stuck on two of them.
“What simple experiment could you perform to predetermine whether or not the color observed for sodium was due to the presence of the sodium ion in the compound or the nitrate in the compound?”
We had to test, Na, K , Ca, Ba, Sr, Li, Cu. They were all mixed with Nitrate.
I thought about this and I thought that when you test all of them, if it was Nitrate then they would all be the same color. Since they were all different colors (all the elements I tested)
Secondly,
A random question I have.
Does higher energy mean longer energy change?
What factor or variable does the energy associated with a specific colour of light depend on?
These two I have no clue. The first one is just something I was thinking about. The second one is on my lab but I have NO IDEA what to do. If you can even give me something to think about it would give me a lead.
