|
|
||||
|---|---|---|---|---|---|
| solvent | the substance present in the greatest quantity
🗑
|
||||
| ionic compounds dissolving in detail | each ion dissociates from the solid structure and disperses throughout the solution
anions are attracted to the partial positive end of water
cations are attracted to the partial negative end of water
🗑
|
||||
| what do ionic compounds do when they dissolve in water | they ionize or form ions
🗑
|
||||
| solvated | when ions are completely surrounded by solvent molecules to prevent them from recombining and to allow them to disperse uniformly throughout the solution
🗑
|
||||
| aqueous solution | solution in which water is the solvent
🗑
|
||||
| nonelectrolyte | substance that does not form ions when in aqueous solution
aqueous solution cannot conduct electricity
most molecular compounds
🗑
|
||||
| electrolyte | substance whose aqueous solution contains ions
aqueous solution can conduct electricity
ex. ionic compounds, some molecular compounds
🗑
|
||||
| precipitation reactions | result in the formation of an insoluble product
follow the pattern of exchange reaction
🗑
|
||||
| what is the insoluble product called | precipitate
🗑
|
||||
| important notes about molecular equations | 1. This equation only contains compounds; not ions!
2. A precipitate must form for a reaction to occur!
🗑
|
||||
| what does not separate into ions in complete ionic equations | the precipitate does not separate into ions (remains a compound)
🗑
|
||||
| important notes about net ionic equations | 1. This equation only shows ions and compounds directly involved in the reaction (formation of a precipitate).
2. If every ion in a complete ionic equation is a spectator, no reaction occurs!!!!!!
🗑
|
||||
| another name for acids | proton donors (not organ donors)
🗑
|
||||
| bases | substances that accept/react with H⁺ ions and produce OH⁻ ions when they dissolve in water
🗑
|
||||
| bases that do not contain OH- | accept H⁺ ions
proton acceptors
ex. NH₃(aq) + H₂O(l) ↔ NH₄⁺(aq) + OH⁻ (aq)
🗑
|
||||
| substances that are insoluble in water cannot be | electrolytes
🗑
