  • bond - Bonding in the phosphate ion - Chemistry Stack Exchange
    Simply put: To make PO4 you must start with a neutral P and three O with a -1 charge and one O with a neutral charge The phosphorus can make 4 bonds by hybridizing The phosphorus hybridizes to sp3 by loosing one electron to the neutral O This creates four oxygen atoms that have a -1 charge and one Phosphorus atom with a +1 charge total charge -3
  • How can Phosphate be charged at -3? - Chemistry Stack Exchange
    Stack Exchange Network Stack Exchange network consists of 183 Q A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers
  • Reading Salifert PO4 Test - Water Chemistry - Nano-Reef Community
    That would put something around 03 ppm PO4 to 5ppm NO3 at a good ratio As long as it looks closer to 03ppm than adjacent levels, it is good If you aren’t suddenly having issues from elevated PO4, which I’d imagine you would have less trouble differentiating colors from those levels, the exact reading isn’t critical
  • Difference in total phosphate and total phosphorus of biomass
    Orthophosphate, I understand, to be $\ce{PO4^3-}$, the simplest form of phosphate that is readily available for biological use by plants and algae It is an inorganic form of phosphate It is an inorganic form of phosphate
  • Phosphates Functional Group - Chemistry Stack Exchange
    Phosphate $\ce{PO4^3-}$ is an anion of the phosphoric acid $\ce{H3PO4}$ Term phosphate comes from a salt, for instance a sodium phosphate $\ce{Na3PO4}$ $\ce{Na+}$ are bound with a $\ce{PO4^3-}$ through ionic bonds No electron sharing To annotate specific moieties of a molecule skeleton, a chemical group term is used
  • Dosing Nitrate Nitrogen on purpose? - Nano-Reef Community
    The theory is that no3 is reduced to the point where po4 reduction stops The Redfield ratios state that consumption of no3 to po4 is 16:1 If you don't have a 16:1 no3:po4 ratio, po4 reduction stops And once no3 is depleted, po4 will rise And until the ratio is corrected, po4 will continue to rise
  • Correct reaction for formation of magnesium pyrophosphate
    $\ce{Mg(NH4)PO4\cdot 6H2O -> Mg2P2O7 + NH3 + H2O}$ We can easily balance this equation through atom balances Placing $2$ before the magesium ammonium phosphate balances both magnesium and phosphorus; then the coefficients on ammonia and water are rendered by balancing nitrogen and oxygen With all elements in fixed oxidation states the balance
  • bond - Polarity of the phosphate ion? - Chemistry Stack Exchange
    There are multiple different things to consider for phosphate $\ce{PO4^3-}$: The bonds themselves Each of the four $\ce{P-O}$ single bonds is polarised towards the oxygen
  • Nomenclature of polyatomic ions - Chemistry Stack Exchange
    Phosphate is $\ce{PO4^3-}$ thus phosphite is $\ce{PO3^3-}$ Chlorate is $\ce{ClO3-}$ thus chlorite is $\ce{ClO2-}$ If your ion includes a hypo- prefix, subtract another oxygen from the -ite species, leaving the rest unchanged
  • Red Sea No3:Po4-X??? - Beginners Discussion - Nano-Reef Community
    Hi reefers Has anyone used Red Sea No3:Po4-X before? i have been cycling a new tank for a week now (Fluval evo 13 5) with live sand and live rock ther is about 12 gallons of water volume I got the No3:Po4-X free with my Red Sea Coral Pro Salt I’m dosing about 0 5ml daily and just recently toda
