HNO3 ratio: • Constant concentration of HNO3 at 8 M with HF variation from 2.8 M to 14 M. • Constant HF concentration at 14 M with HNO3 variation from 1.8 M to ... A compact protective film is formed on the copper/solution interface as the tested drug molecules replace the adsorbed H2O molecules on the copper surface. May 17, 2018 ... Since you want to go from 5.0 M to 1.0 M concentration, and you want 225 mL of the resultant solution, you want to get 15 of the concentration. The molal concentration (m) is defined as the number of moles of solute per kilogram of solvent. In this case, the solute is HNO3 and the solvent is water. 1). Determine the pH of a 0.0034 M HNO3 solution. pH = -log[H+] = -log(0.0034) = 2.47. 2). Determine the pOH ... 0.05 M HNO3. 492. 470.4. 50. 0.5 M HNO3 + 0.1 M HNgNO3. 2,000. 1,960. 30. 0.01 M HNO3. 1,238.4. 1,259. 50. 0.05 M HNO3. 598. 622. 40. 0.05 M HNO3. 504. 515. 50. ... and 0.1 M 2 (open markers) in FS-13 solvent. Aqueous phases contain 0.001 M Eu(NO3)3 and 0.010 M HNO3. The solid lines depict slopes of m = 0 and m = -2,.
