Solutions and Solubility Flashcards
(21 cards)
Solution
Homogeneous mixture
3 Types: Liquid (sugar in water), Gaseous (Air; O2 and N, etc), Solid (Brass; Zn + Cu)
Saturated Solution
The solvent has dissolved the max amount of solute possible at that temp.
Unsaturated Solution
More solute can be dissolved in the given volume of solvent
Supersaturated Solution
Artificially created solution; involves gentle heating and cooling
Generally unstable/fragile
Solubility
The ability of a solute to dissolve in a solvent, which forms a solution
Hydration
Add water
Solute
Substance being dissolved (smaller quantity)
Solvent
Present in greater amount (not always liquid)
Dilute Solutions
A very small amount of solute
Strong/Weak Acids
Strong; dissoiates completely when in aqueous solution (99% of the time)
Weak; majority of molecules remain undissociated (2.6%)
Strong/Weak Bases
Strong Bases: Dissociates in water 99.9% of the time
Weak Bases: Dissociates only slightly (2.6%)
pH Scale
Used to describe acidity of solutions (based on H+ in solutions)
Spectator ion
A lab technique that puts to use neutralization of acids and bases to determine the concentration of an unknown solution
Titration
Uses neutralization of acids and bases to determine concentration of an unknown solution
Hydronium Ion
Hydrated protons (H3O-)
Aqueous Solution
Ionic Character
Electrolyte
Arrhenius Theory (Acids and Bases)
Bronsted Lowry Theory (Acids and Bases)
Concentrated Solutions
More solute than solvent.
