3. pH is a measure of the concentration of water molecules that have dissociated into ions. This number is very small, so very, very small that it is annoying as ^%$@#% to write out. Therefore, we convert this by equation to a measure of "pH" to make is easier to describe the level of ionization. It is a characteristic of water that the product of the concentration of each ion of water will equal 10¹4 (i.e. in aqueous solutions, [ H+] x [OH-] = 10", where [] is used to represent concentration in moles/liter). a. We can write that several ways (fill in the missing parts): 10¹4 = 10^-14 = 1/10^ = 1 in b. At neutral pH, the concentration of H+ = 10^-7. But we all hate exponents, especially negative exponents, so we use this equation to make a pretty pH number pH=-log [H+]. pH = -log[ 10^-7] = (review the Bioskills appendix to practice using
