Unit 24 - Solubility and Ksp
Terms in this set (26)
the process of surrounding solute particles with solvent particles to form a solution.
the separation of ions that occurs when an ionic compound dissolves.
a substance that is dissolved in a solution.
the substance in which the solute dissolves (largest portion of a solution).
a homogeneous mixture formed when one substance dissolves into another.
a solid product which forms from aqueous reactants.
capable of being dissolved to a relatively high extent.
capable of being dissolved, but to a small extent.
incapable of being dissolved to any significant extent.
the number of moles of solute per liter of solution, form of concentration.
molarity of a solute in a saturated solution. Equivalent to "x" in the RICE for a dissolving equation.
common ion effect
a decrease in the solubility of an ionic compound caused by the addition of a common ion.
type of substance which dissociates and then solvates. Made of metals and non-metals.
type of substance which, when soluble, tends to solvate without dissociating. Made of two or more non-metals.
type of substance which dissociates (partially or fully) and then solvates. Gives protons in solution.
adjective which describes a solution containing the maximum amount of solute possible at a given temperature.
net ionic equation
an equation for a reaction in solution showing only those particles that are directly involved in the chemical change (no spectators!).
a reaction equation that shows the complete chemical formulas of all reactants and products, including the spectators.
adjective which describes a solution in which the pH is NOT allowed to change.
solubility product constant, the equilibrium constant for the dissociation of an ionic compound in water.
ion product quotient. Used to predict whether a solution is sat, unsat, or supersat.
Qsp > Ksp, the solution contains too many dissolved ions. Precipitation will occur in order to reach equilibrium (shift left).
Qsp = Ksp, the solution contains the maximum possible ion concentrations and is at equilibrium.
Qsp < Ksp, the solution is not yet saturated and will continue to dissolve solute. Equilibrium will shift right to produce more dissolved ions.
a technique used to separate ions in aqueous solutions by adding a reagent which will precipitate specific ions while ignoring others.
fluid that has passed through a filter, typically containing the spectator ions. Anything which has NOT become part of the precipitate in an aqueous reaction.
