NaHCO3 is sodium bicarbonate but the IUPAC name is sodium hyrogen carbonate. (NH4)3PO4 is ammonium phosphate NH4OH is ammonium hydroxide but you need to be aware that there is no such animal as NH4OH. It REALLY is a solution of NH3 in water or NH3(aq). That ionizes to produce ...

That's what was confusing to me, too, no conjugate acid/base. The NH4NO3 is the salt of a weak base and a strong acid, so NH3 solution with NH4NO3 would be a buffer. And there was no polyprotic acid or base there either. By the way, you mentioned that NH4NO3 was the salt of ...

The problem is confusing IF you have posted it correctly. Have you added 1.04 mols HA or have you added 50.0 mL of 1.04M HA? Same with NH4OH. Is that 0.90 moles or 50.0 mL 0.90 M NH4OH? Actually it doesn't make any difference. The LR is NH4OH with either scenario.

Chemistry
By adding the NH3 solution (actually NH4OH), you are creating... NH4+ and OH- so you add those two ions to the metal and chloride ions. YOu know the product of ammonium and chloride will be soluble, so any insoluble product will be the metal oxide compound, for instance, ...

I will do the third one. NH4OH: .010l*.3=.0030 moles HCl: .030*.1=.003 moles they are all react, no excess acid or base. So, pH=7 the fourth one: moles base: .0030 moles acid: .040*.1=.004, or an excess of acid of .001moles volume+ 10ml+40ml=.050 liters concen acid: .001/.050...

Chemistry-Experiment
I don't know what nitrite acid is so I can't help you with the second part. The first part is this. Mg^2+ + 2OH^- ==> Mg(OH)2. 1) Ksp = (Mg^2+)(OH^-) NH3 + H2O ==> NH4^+ + OH^- 2) Kb = (NH4^+)(OH^-)/(NH3) [note: my NH3 takes the place of your NH4OH] 3) NH4Cl ==> NH4...

DrBob222-Questions
CaCl2 = Calcium ion and Chlorite ion You named MgCl2 magnesium chloride on the last post. Why would you not name this one calcium ion and chloride ion. Na2O = Sodium ion and Oxygen ion sodium ion and oxide ion AgCl = silver ion and chlorine ion silver ion and chloride ion ...

chemistry
Why does the equivalence point occur at different pH values for the four titration studied? the four titrations were: 1. HCL with NaOH 2.HC2H3O2 with NaOH 3. HCl with NH4OH 4. HC2H3O2 with NHOH Okay so equivalence point is when the number of moles of acids and bases are equal...

AlCl3(aq)+ NH4OH(aq)-> Al(OH)3(s) + NH4Cl(aq) AlCl3(aq)+ 3NH4OH(aq)-> Al(OH)3(s) + 3 NH4Cl(aq)... is balanced-- Now total ioic?? Is this right?? : Al +3Cl+3NH4 +OH --> Al+ 3OH+ 3NH4+ 3Cl Crossing out on both sides I end up with OH --> 3OH I do not know what to do ...
