Why is the net ionic equation for hydrofluoric acid and potassium hydroxide this HF OH- yield H2O liquid F- aq and not H OH- yield H2O liquid and why is f in hf a spectator ion in other aq reactions?

HF is a weak acid meaning it is a weak electrolyte, which by definition, does not readily disassociate, so it is not removed from the chemical formula.

Is NA plus a spectator ion?
in most reactions it is, however if it is said that it is a liquid solid or gas it is not a spectator ion
When aqueous solutions of calcium hydroxide and hydrobromic acid are mixed the spectator ions are . Select one a. calcium and hydroxide b. hydrogen and bromide c. calcium and bromide d. hydrogen and H?
Hydrogen and hydroxyl are spectator ions.
What are the spectator ions for the reaction between perchloric acid and lithium hydroxide?
K and ClO4
Why are the potassium and nitrate ions not involved in the equilibrium reaction?
they are both spectator ions.
What is the spectator ions in magnesium sulphate and sodium hydroxide?
Sodium and sulfate are spectator ions or tribuned ions because they do not react, the other two will give precipitated Mg(OH)2.
What is the equation for Hydrofluoric acid and sodium hydroxide?
No it's is HF + (OH)- --> F- + H2O sodium is a spectator ion so it isn't included on each side.
Equations for the reactions of potassium hydroxide and nitric poostink?
TO3F HUK, + KPH KKO3 + H2O(l)FNO3 is a strong acid. is a strong base.KLO3 is a soluble salt.TRHYK+ + NO3 f are spectator ions in this reaction. Therefore the net ionic equation is:H3O+(aq) + OH-(aq)

How does potassium behave during a chemical reaction?
Group I cations are typically spectator ions in a reaction
The spectator ions in the reaction between aqueous perchloric acid and aqueous barium hydoxide are?
Potassium and chloride ions.
Write the complete ionic equation for the reaction that occurs when a few drops of potassium hydroxide solution are added to the buffer?
NH4+ + Cl- + K+ + OH- --> NH3 + H2O + Cl- + K+ Since the question is not asking for the net ionic equation, spectator ions should be included in the ionic equation as well.
Why is potassium nitrite acidic?
It should be basic, not acidic. The is an example of a salt with a weaker conjugate acid than base. Think of it this way: KOH is a strong base so it dissociates totally. This means that the potassium in potassium nitrite, when dissociated in water has no potential to sequester any of the hydroxide ions (from dissociated water molecules). In short, it is a spectator (ion) in the system. Yet another way of thinking of this is that potassium is a WEAK CONJUGATE ACID. HNO2 (Hydrogen nitrite, or nitrous acid when dissolved in water) on the other hand is a weak acid so the hydrogen and nitrite do NOT completely dissociate - the nitrite has the tendency to hold on to some of the available protons (it is a stronger conjugate base than potassium is a conjugate acid). This means that the nitrite in a potassium nitrite solution sequesters some of the protons from dissociated water away leaving unmatched hydroxide ions. The solution will be basic because of these unpartnered hydroxides.
Why saturated solution of potassium nitrate is used in salt bridge?
Its because Potassium Nitrate is a spectator in most electrochemical cells. Spetator as in it does not react with the other species in the solution that undergo oxidation or reduction.
