osmosis lab

sfsdfsdf

to prevent osmosis

equal pressure needs to be applied

greater solute concentration

the greater the osmotic pressure

if a cell take on too much water

lysis

osmolarity

number of particles in a liter of solution

normal osmolartiy

275-295

isosomotic

equal

hyperosmotic

solution with less water

hypoosmotic

solution with more water

tonicity

if solution can pass membrane

tomicity compares

solution to cell

isotonic solution

same solutes in an dout

hypertonc solution

less water than solutes

hypotonic solutions

more water than solutes

crenate

hypertonic solution , shrivels up

lysis

hypotonic solution bursts

percent change equation

(final weight - initial weight / initial weight) x 100
