properties of solutions

understanding properties of solutions

what does the polarity of water allow it to form

hydrogen bonds

what is the measure of how well similar molecules stick to each other

cohesion

what does the cohesiveness of water allow it to do

travel through small capillaries without using energy

how does cohesiveness create surface tension

by creating a layer of water molecules on the surface of any body of water

what is a measure of how well different substances stick to each other

adhesiveness

is the formation of a solution from a solute and a solvent a physical or chemical process

physical

how is a solution formed

when one or more solutes dissolves in a solvent

what 3 phases do solutions exist as

• gases

• liquids

• solids

as the solubility of most solid and liquid solutes increases, temperature _________

increases

as the solubility of gas decreases, temperature __________

increases

which type of solution has the maximum possible amount of solute

saturated solution

which type of solution has less than the maximum amount of solute

unsaturated solution

which type of solution allows higher temperatures to dissolve more solute

supersaturated solution

what is the quantity of solute in a given quantity of solution

concentration of a solution

what is the addition of solvent to decrease the concentration of solute in a solution called

dilution

which 2 units are used to express very low concentrations

ppb or ppm

what is the molarity of a solution dependent on

temperature

what is the movement of a substance from high concentration to low concentration

diffusion

what is the movement of water from high concentration to low concentration

osmosis

what does water move through in a membrane

aquaporins (pores made of protein)

which type of transport does not require energy

passive transport

does diffusion and osmosis require energy

no

what is the movement against the concentration gradient called

active transport

does active transport require energy

yes
