I need help interpreting this lab result.
Taking an alkaline earth halide hydrate (an unknown white powder), I dehydrated
the chemical over a bunsen burner, so that I was left with only an alkaline
i have determined the amount of chemical (6.1 g) before dehydration, and the
amound of chemical (5.15) after.
Then, I did a flame test in which I took the dehydrated alkaline earth halide
and placed it over a bunsen fire.
The fire turned lime green when in contact with the powder.
Then, I took some alkaline earth halide, and rehydrated it to create an
aqueous solution. I made two test tubes of this solution.
In one, I added drops of Na2CrO4 (Sodium Chromate), forming (I think) a white
percipitate that begun to create a snow globe atmosphere.
In the other, I added drops of AgNo3 (Silver Nitrate), forming a milky lime
green/yellow percipitate (close to the color of a sick person's mucas).
Those percipitates may be the other way around -- I will double check to make
So the question is - What alkaline earth halide has these properties?
Where can I find information about percipitates where I can tell if
AgNo3 mixes with such and such alkaline earth halide, then the halide must be...
After, I will do analysis to decide exactly how much water is in the oringinal
