Unit 2 Flashcards
(20 cards)
Are defined as homogeneous mixtures of two or more pure substances.
Solutions
Present in greatest abundance
Solvent
All other substances are
Solute
When water is the solvent, the solution is called
Aqueous solution
Water surrounds the separated ions
Dissociation
A substance that dissociates into ions when dissolved in water
Electrolyte
May dissolve in water, but it does not dissociate into ions when it does so
Non electrolyte
Dissociates completely when dissolved in water
Strong electrolyte
Only dissociates partially when dissolved in water
Weak electrolyte
Does not dissociate in water
No electrolyte
When two solutions containing soluble salts are mixed, sometimes an insoluble salt will be produced. A salt “falls” out of solution, this is called
Precipitate
List the reactants and products without indicating the ionic nature of the compounds
Molecular equation
All strong electrolytes(strong acids, strong bases, and soluble ionic salts) are dissociated into their ions
Complete ionic equation
To form the net ionic equation, cross out anything that does not change from either side
Spectator ions
Reactions between an acid and a base are called
Neutralization reactions
The amount dissolved is called
Concentration
Is one way to measure the concentration of a solution
Molar it yet
Is an analytical technique in which one can calculate the concentration of a solute in a solution
Titration
A solution of known concentration is used to determine the unknown concentration of another solution
Standard solution
The reaction is complete at the
Equivalence point
