water properties Flashcards
molecule with slightly positive charge on the hydrogen side and a slightly negative charge on the oxygen side, has electrons near it at all times
polarity
attraction between a hydrogen atom with a partial positive charge and another atom with a partial negative charge
hydrogen bond
attracts like substances, water loves water
cohesion
attraction between substances, water loves glass
adhesion
blend of two or more substances that preserve their identities and are turned into solutions
mixture
evenly distributed mixture
solution
substance being dissolved to make a solution
solute
solute in it to make a solution, water is the #1 of this
solvent
suspension
how acidic or basic something is
pH scale
hold together compounds
chemical bonds
involve the transferring of electrons
ionic bonds
involve sharing electrons
covalent bonds
last right of electrons
valence shell
the attraction (pull) of molecules on the top of a liquid (water) that allows it to resist external forces due to its cohesive nature
surface tension
water loving and hating , examples: dawn soap, cell membrane
amphipathic
not attracted to water, non polar
hydrophobic
attracted to water, polar
hydrophillic
