Re: Query




> Sir, you have mentioned in example 14 that we can estimate the
moles of calcite, dolomite and Cation exchange sites in the
aquifer per liter of water. Sir how can we find out the number of
cation exchange sites. Is it by multiplying the CEC of clay with
the weight of rock per liter of solution? Kindly help me in this
regard.

Yes. The number you want is the number of equivalents of exchange sites per
liter of water.
