You perform an uknown nitrate test.............?

Question

After combining the nitrate with different solutions, you can't produce a precipatate. What are some cations that could give these result and how could you determine what cations were present in this salt?

Answer 1

All nitrates are soluble. You would need to consult a table of solubilities to see what other ions you could use to precipitate out the cations.

Ex: If you had silver nitrate in a solution you could add something with a halide ion such as sodium chloride. The silver ion would precipitate out with the chloride ion. If no ppt forms with the sodium chloride you know it was not silver ions.

Then look for other ions that you could test for.

Answer 2

in case you have 4 goldies i'm assuming you have an sufficient tank length, of a minimum of 50+ gallons as goldfish require 10-15 gallons according to fish. I additionally propose a filter out that handles double the capacity of your tank. I even have 4 goldies in a fifty 5 gallon with a a hundred and ten gallon rated filter out. with out an sufficient tank and filtration equipment you're putting your self up for ill and dying fish. Is your tank cycled? A biking tank could desire to be examined another day. A cycled tank could be examined as quickly as each week. All fish proprietors could desire to have a drop attempt kit reachable for pH, ammonia, nitrites, nitrates and hardness/softness. Goldfish require cooler water of 60-seventy 5 F. They require alkaline water, that's the pH and because a 7.0 is independent they require a pH of 7.2-7.8. you will could desire to ascertain you get a kit with a 'intense variety' pH attempt for this. The ammonia desires to be 0 ppm, nitrites 0 ppm and nitrates under 20 ppm. If any of those are off it could desire to reason tension, ailment or perhaps dying. the only thank you to dazzling water high quality matters is with water variations...50% emergency variations in intense situations with 20-25% on a daily basis or another day till the issue is corrected. you additionally can use Kordon's AmQuel Plus to detoxify any ammonia or nitrites in the water so as that the fish don't get ill yet use this with warning in a biking tank for the reason which you would be neutralizing it and not permitting the nitrogen cycle to end. stable success.
