The cations on an exchangeable sites of a 30 g soil were displaced by repeatedly washing by a salt and found to be 20 mg ca+2, 1.0 mg na+1, 39 mg k+1, 12 mg mg+2, and 18 mg al+3. the ph of the soil was 5.0. calculate the cec (cmolc/kg), percentage base saturation (pbs) and percent acidic saturation (pac) per kg of the soil.

explanation:

crosscutting concepts have application across all domains of science. as such, they are a way of linking the different domains of science. they include patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change.
