To perform the test, clean a test tube with pure water. Add 20 drops of your test solution to the test tube, acidify it with a few drops of dilute nitric acid, then add a few drops of silver nitrate solution. The nitric acid reacts with, and removes, any other ions that might conf...

How are the formulas for nitrate and nitrite similar? How are they different? Nitrates: Nitrates act as one of the most important and widely used vasodilators. Nitrates play a significant role in the improvement of the flow of blood and this ultimately allows the blood that ...
considering initially all candidates for every tube and removing not suitable. e.g. if lead iodide formation is detected for two tubes, remove all candidates for them that contain neither lead nor iodide. and as lead can be only in one of these two tubes, remove the lead nitrate candidate ...
i am re-learning how to take care of my fish so thanks
The Lewis Structure for the Salt NaCl depicts two ions with complete octets in their outer shells of electrons. As a result, there is a positive charge on sodium (due to one lost electron) and a negative charge on chlorine (due to one electron gained).
As for fish, high nitrate levels can cause respiration problems in fish, lower or eliminate the ability to breed, resist disease, and lower activity of aquarium inhabitants. My own experience and test have shown immediate problems with nitrate as low as 20 ppm with cephlapods in marine aquariu...
