Reactions In Aqueous Solutions Flashcards
Aqueous Solution
When water is the solvent
Dissociation of ionic compounds
In water, ionic compounds dissociate for water to surround the seperated ions
Solavation
All substances dissolve by solvation surrounding the solute by solvent.
Electrolyte
Substance that dissociates into ions when dissolved in water
Non electrolyte
May dissolve in water but does not dissociate into ions when it does
All ions are strong electrolytes
Electrolytic behavior of molecular compounds
Strong electrolytes are strong acids
Weak acids and bases are weak electrolytes
The rest are non electrolyte
Strong electrolytes vs weak
Dissociates completely in water
In weak, electrolytes only partially dissociate when dissolved in water. Creates chemical equilibrium equ
Soluble ionic compounds
- Grp 1A
- Salts with NH4, NO3-, CLO3-, C2H3O2-
3.Salts with CL, Br, I except those with Ag+, Pb2+, Hg2+, 2
4 Sulphates except Pb2+, Ca2+, Sr2+,Hg2+,2, Ba2+
Insoluble ionic compounds
- All OH-, metal oxides (O2-) except grp 1A and Ca2+, Sr2+, Ba2+
- Salts with PO3-, 4, SO2-,3, S2- except NH4+
Precipitation rxn
2 solutions containing soluble salts are mixed and an insoluble salt is produced
Metathesis
Exchange rxn
Appears as though ions in reactant compounds exchange
Acids
Substances that ionize in Aqueous Solutions to form H+ ions
Proton donor as it has H+ ions
Base
Substances that accept H+ ions
Increase OH- in dissolved water
Neutralization rxns
Acid+base rxns
When base is: metal hydroxide, water, salt = ionic compound is produced
Neutralization gas formation
Carbonate /bicarbonate + acid = salt, CO2, water
