Solutions- Science Flashcards
what makes a solution concentrated
if it has a large amount of solute dissolved
what does it mean if a point is under a line (on a solubility curve)
it is unsaturated
why is water polar
because it is asymmetrical
difference between a solute and solvent
a solute is being dissolved, solvent is what is dissolving
what does nonpolar mean
the even distribution of charges on a molecule
what are the 4 ways to change solubility of a solute
temperature, pressure, molecular size, polarity
what is polarity
the uneven distribution of charges on a molecule
what is an element
a pure substance, homogeneous throughout; only one kind of matter present
what is a suspension
when solute is suspended in solvent for a period of time
mixture
physical, no bonds breaking
how to calculate molarity
molecular mass (element, # of atoms, atm. mass, total) over 1L of solvent
what is an unsaturated solution
when the solvent can still dissolve more at that temperature
a _________ atom will control because it has larger ___________.
larger; energy shell
what is a compound
a pure substance, homogeneous throughtout made from 2 or more elements, compounds, or both physical
what does it mean if a point is on a line (on a solubility curve)
it is saturated
