From what I've been told, because HF is a weak acid and therefore a weak electrolyte you are not supposed to break it up into cations and anions. Not sure how you would be getting F- as a spectator in other aq reactions, unless there's an extra rule that I simply haven't been taught.
In the case of HF and KOH, HF (a weak acid) does not fully dissociate but rather undergoes a partial ionization to form F- and H2O. F- is a spectator ion in other aqueous reactions involving HF because it remains in solution and does not undergo any further chemical reactions. The net ionic equation for HF and KOH is specific to the equilibrium between these two compounds.

Can the total ionic equation shows the net change in the equation after spectator ions been removed?
Yes, the total ionic equation shows all the ions involved in the reaction, including the spectator ions. To find the net ionic equation, you can remove the spectator ions from the total ionic equation to emphasize the ions that participate in the actual chemical change.
What happens to a spectator ion in a net ionic equation?
A spectator ion does not participate in the chemical reaction and remains unchanged on both sides of the equation. It is typically omitted from the net ionic equation since it does not contribute to the overall reaction.
How is a net ionic equation written from a ionic equation?
the spectator ions are removed
Can the complete ionic equation and the net ionic equation for a double replacement reaction ever be the same?
Yes, the complete ionic equation and the net ionic equation for a double replacement reaction can sometimes be the same. This occurs when all reactants and products are fully dissociated into ions in the reaction, leaving no spectator ions. In such cases, the complete ionic equation and the net ionic equation will be identical.
What components are included in a net ionic equation?
A net ionic equation includes only the ions and molecules that participate in the chemical reaction. Spectator ions, which do not participate in the reaction, are not included in the net ionic equation. The components included are the reactant ions that form the products of the reaction.

How is a net ionic equation written in a complete ionic equation?
To write a net ionic equation from a complete ionic equation, you remove the spectator ions that appear on both sides of the equation. The remaining ions that participate in the reaction are then included in the net ionic equation. This simplifies the equation to show only the ions that undergo a chemical change.
What is a net ionic equation what species are shown in such an equation and which species are not shown?
A net ionic equation shows only the ions that participate in a chemical reaction, excluding spectator ions that do not participate. The species shown are the ions involved in forming products in the reaction, while the species not shown are the spectator ions that remain unchanged during the reaction.
What information does a net ionic equation give that a complete ionic equation doesn't show?
A net ionic equation shows only the ions that are directly involved in the reaction, excluding spectator ions. This helps focus on the key components of the reaction, highlighting the actual chemical change that occurs. In comparison, a complete ionic equation includes all ions present in the reaction, including spectator ions that do not participate in the chemical change.
What chemicals are present in a net ionic equation?
The are only soluble ions without spectator ions.
What is the net ionic equation for HPO42- and HCl.?
The net ionic equation for the reaction between HPO42- and HCl is: HPO42- + 2H+ -> H2PO4- + Cl-. The spectator ion in this reaction is Cl-.
The chemical equation that shows all ionic reactants and products is known as?
The chemical equation that shows all ionic reactants and products is known as an ionic equation. In this type of equation, only the species that are involved in the reaction are shown as ions, while spectator ions are omitted.
