- Consider forest soil in contact with water containing 3.9 μg/L. Use the Freundlich relation to determine the equilibrium concentration of adsorbed cadmium. Assume KF = 0.0324 L/g and nF= 0.82. Why is it appropriate to use the Freundlich relation in this case?

7. The behaviour of lead in soil/water systems has been described in terms of Langmuir adsorption. From laboratory experiments using 'pure solids, the following values for Langmuir parameters have been estimated For clay b = 3200 L mol- Com = 4x10-4 mol g For organic matter b = 10 000 L mol-' Csm = 4x10-4 mol g -7 (a) Use these values to calculate the concentration (in mg L or ppb) of water-soluble lead in equilibrium with clay containing 5...

Tank 1 initial contains 10 L (liters) of water and 355 g of salt, while tank 2 initially contains 90 L of water and 345 g of salt. Water containing 40 g/L of salt is poured into tank1 at a rate of 4 L/min while the mixture flowing into tank 2 contains a salt concentration of 20 g/L of salt and is flowing at the rate of 1...
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
