Moss near brooks secrete organic acids.
Moss near brooks secrete organic acids. Assume that a specific type of sphagnum solely secrets HL- of the diprotic acid maleic acid (H2L, pKa1=1.92, pKa2=6.22) in a brook. Calculate the pH-value and the exact concentration of H2L, HL- and L2- during equilibrium if the total content ([H2L]+[ HL-]+[ L2-]) is 0.0001 M.
