Intro Solution Chemistry (APAC)
a homogeneous mixture of two or more substances
a liquid substance capable of dissolving other substances (majority of the solution)
the dissolved substance in a solution
Density of Water
1.0g/mL (unless stated otherwise)
Moles of solute/L of solution, unit: mol/L
Mole Fraction (X)
Moles of component/∑ moles, unitless
weakening (reducing the concentration) by the addition of water or a thinner
No more solute will dissolve
More solute will dissolve
More solute is dissolved than should be possible under normal conditions
How does something become supersaturated?
1. Temp - Heat: particles move faster, more solubility
Cool: solute won't necessarily precipitate
2. Evaporation - Saturated soln evaporates; V down, C up
M(i)V(i) = M(f)V(f)
the strength of a solution
