CATION EXCHANGE CAPACITY BASE SATURATION

What Is Cation Exchange Capacity? The cation exchange capacity of a soil is a measurement of its ability to bind or hold exchangeable cations. In other words, it is a measure of the number of negatively-charged binding sites in the soil. Cation Exchange Capacity Helps to Characterise Soils The cation exchange capacity helps characterise the soil type under consideration.

called the cation exchange capacity (CEC). These cations are held by the negatively charged clay and organic matter particles in the soil through electrostatic forces (negative soil particles attract the positive cations). The cations on the CEC of the soil

Exchange acidity = Al + H . Example: Al (cmol/kg) = 0.5 . H (cmol/kg) = 1.5 . Exchange acidity = 0.5 + 1.5 = 2.0 cmol/kg . CEC can be measured directly (called measured CEC) by measuring cations exchanged from an extracting solution. More commonly CEC is calculated as the sum of the four main cations, or the base cations (called CEC by bases).

Cation exchange capacity practice problems

This makes the mole of charge (mol c) a handy unit when discussing cation exchange capacity in soils. In soils, a mole of anions or cations is too big a number to be easily manipulated. The most common unit when calculating exchange capacity of soils, clay minerals or organic matter is centimoles of charge (cmol c /Kg soil).

How to calculate the cation exchange resin capacity?

If I have a cation exchange membrane and need to remove 2 g/L of sodium, how much resin would I need. I used the amount of substance of $\ce{Na}$ to calculate the amount of substance of $\ce{SO3H-}$ needed for complete sodium removal. But this will not give me the correct mass since the resin is a polymer with that functional group attached.
