One way to distinguish between zinc nitrate and calcium nitrate is through a flame test. When heated in a flame, zinc nitrate emits a green color, while calcium nitrate emits a red color. Additionally, chemical tests such as adding a carbonate compound can help differentiate them. Zinc nitrate forms a white precipitate with sodium carbonate, while calcium nitrate forms a white precipitate that dissolves in excess carbonate.
You should be able to providing ammonium nitrate and water is the only ingredients. Ammonium nitrate is a powerful oxidizer meaning it will burn things on contact like your plants,there roots and your flesh. I've never dealt with cold packs so I have no idea what the final concentration is after they are used. Diluting it significantly like 20 to 1 and testing a small amount on an expendable plant would be advisable. Pure ammonium nitrate only supplies nitrogen. Your plants also need potassium and phosphorus and the ratios vary from plant to plant. If you want to do some weird science try diluting it then mixing in a few handfuls of wood ash for the potassium,pee in it a few times for the phosphorus then test some on your plants. I use nitrogen based fertilizers mixed with ash from my fire place and pee on my outdoor plants all the time when no one is looking and they are doing great. My neighbors think I have a green thumb but I'm allways tempted to tell them, No. I Have a green p*&@#r. Good luck.
The nitrate ion imparts no color to a solution.
Cupric nitrate typically produces a blue-green flame when burned.
The flame of barium nitrate typically produces a pale green color when burned. This green color is a characteristic flame test color for barium compounds.

You would want to use spreader setting 3.25
Overseeding -- 7 1/2 New Lawn/ Bare spot -- 18 but it would be best to go over the lawn twice at setting 7 1/2 in perpendicular directions.

The nitrate ion (NO3-) is colorless.

For a Scott's Speedy Green 2000 spreader, the recommended setting for applying 19-19-19 fertilizer is typically around 5 to 6. However, it's important to check the manufacturer's guidelines or refer to the specific fertilizer bag for exact settings, as they can vary based on the product and application method. Always conduct a test run on a small area to ensure even distribution.
Nickel nitrate typically appears as a green crystalline solid.
Copper II nitrate typically produces a blue-green flame when burned.
