Solid aluminum hydroxide at a concentration of 10 mg/L is used to treat surface water in a precipitation-dissolution process. When chemical equilibrium, at a neutral pH is reached in the reactor of this system, what will be the molar concentration of dissolved al available to carry out this process? AI(
Find the equilibrium concentration of aluminum ions in pure water at 25 degree C caused by the dissociation of Al(OH)_3. Express the answer both in units of M and mg/L. Find the equilibrium pH value if copper ion (Cu^2+) concentration in water is 1.2 mg/L. The copper ion is dissolved from Cu(OH)_2. Calculate the equilibrium concentration of dissolved oxygen in mg/L in 10 degree C water (a) at msl (mean sea level), and (b) at 600 m elevation.
1a.) From water sample, 10 mg/L HCO3- as CaCO3, 10 mg/L CO3- as CaCO3 and 50 mg/L Ca+ as CaCO3 were measured. pH was near neutral. What is alkalinity? _____ mg/L as CaCO3 1b.) From water sample, 10 mg/L HCO3- as CaCO3, 10 mg/L CO3- as CaCO3 and 50 mg/L Ca+ as CaCO3 were measured. pH was near neutral. What is alkalinity? _____ mg/L as CaCO3 1c.) Calculate Ksp = _____ A2BO3 ->2A++ BO32- Molar concentration of A+ = Molar...
The total hardness a water sample is 200 mg/l as CaCO3. The calcium (Ca2+) concentration is 50 mg/l. Calculate the magnesium (Mg2+) concentration, in mg/l.
Calculate the % Al in the sample. Preparation of a stock solution of aluminum. Accurately weigh out approximately 1 g of the aluminum foil. Tear it up into small pieces, place the pieces into a covered 250 mL beaker and add 60 mL of 6M HCl. This should be carried out in the fume hood because the reaction is exothermic and leads to violent frothing and emission of vapors. Cool, quantitatively transfer to a 250 mL flask, rinsing with deionized...
Calculate concentration of O_2 (in mg/L) in surface water in equilibrium with atmosphere (at 25 degree C): K_O2 (25 degree C) = 1.28 times 10^-3 mol/L-atm 20.95% of O_2 in dry air P_H2O (25 degree C) = 0.0313 atm Knowing that O_2 solubility is 14.74 mg/L at 0 degree C and 7.03 mg/L at 35 degree C, estimate O_2 solubility at 50 degree C (in mg/L)
Calculate the steady-state flow rate, Qe in m3/day, and concentration of lake effluent, ce in mg/L, for the following system. The lake is well-mixed with two streams that enter the lake. Evaporation takes place from the lake but because c is not volatile none of it evaporates. QvAP 200 m2/day CEVA,-0 mg/L Q1-8 m3/min 1 4 mg/L QE CE Lake Q2-12 L/s c2-50 mg/L

If you add 30 g of aluminum phosphate to a 1.00 L volumetric flask and bring the final volume to 1.00 L, what would be the concentration of Al^3+ in solution? Assume that the Al^3+ in solution is at equilibrium with AlPO_4(s) and the temperature of the solution is 25 degree C. The pKs for aluminum phosphate is 22. If you add 50 g of aluminum phosphate to a 1.00 L volumetric flask and bring...
