Can bacteria nitrify ammonia if it is bonded to a base?

AI Thread Summary
The discussion centers on the interaction between ammonium ions and nitrifying bacteria in an aquaponics setup. When ammonium ions, such as those in ammonium chloride (NH4Cl), are present, the key question is whether nitrifying bacteria can convert the ammonia into nitrites and nitrates despite being bonded to chlorine. It is clarified that while ammonium salts are initially undissociated in solution, they dissociate into ammonium ions (NH4+) and anions, allowing for the potential conversion by bacteria. The conversation also highlights the importance of selecting an appropriate anion that supports bacterial activity, as some ions, like Fe3+, may not be readily bioavailable and can affect nutrient cycling. The goal is to manage ammonia levels effectively to prevent toxicity in the aquaponics system.

If an ammonium ion is bonded to let's say chlorine for simplicity sake, and NH4Cl is created, can nitrifying bacteria come in and still create nitrites and nitrates from the ammonia if it is bonded to the chlorine? I am asking this because I am planning to make a schematic for an aquaponics set-up and I want to balance the amount of ammonia in the water as possible, in my case with a base not chlorine, in order to be able to add more ammonia at once to the system without the water reaching toxic levels. Thank You!

Can you rephrase your question? It appears you wish to use a different anion than chloride, but the way you've written it, it also appears you think that ammonium salts are undissociated in aqueous solution.
 
Thats true. So the dissociated salts will have no effect since the ammonia is In ion form. Thank you
 
NH4+ is very soluble in combination with most common anions, but not all ions bacteria want to use are nicely soluble. For example, Fe3+ often sediments and concentrations naturally become very low. So siderophores are released to chelate Fe3+ ions away from their salts to make them bioavailable.

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
