Unformatted text preview: proton = H+] The pH scale- 0-14; 7 is neutral -- pH+=pOH-pH is low means high proton/H+ concentration pH is high means low concentration Increasingly acidic increasingly basic pH+>pOH-pH+<pOH-If equal numbers then neutral Negative log scale. Go from pH 4 to 5- negative 10x; 11 to 8 1000x 4. Water moderates temperature a. Water heats and cools slowly-Must break H- bonds/ must form H-bonds b. Water is an effective coolant-Removes heat by evaporation 5. Water is an unusual solid Ice : water is less dense when frozen than liquid water H 2 O solid state: H-bonds become rigid = further apart // expands...
