Consider the following on data on Bell Lake:Period Al (µg /L) total concentration pH1981-1983 106 5.41999-2001 39 6.4
a) Based on the Ksp for Al(OH)3 of 1 x 10-33 what are the highest theoretical concentrations of Al3+ at these pH values, in µg /L?b) How do the theoretical concentrations of Al3+ compare to the measured total concentration of Al in the lake? Explain the difference.
