• Sep 23, 2016 · You prepare a 1L solution of 0.5 M imidazole. (pKa= 7.05). Calculate the pH of the solution after you add 0.1 moles of HCl. I need to create an ICE table. I also know I need to use the Henderson- Hasselbalch equation but I'm confused on what to plug in.
  • What is the pH of a solution in which 224 mL of HCl, measured at 27.2 degrees C and 1.02 atm, is dissolved in 1.5 L of aqueous solution? pH = 2.21 Determine the H3O+ and pH of a 0.100 M solution of benzoic acid

  • Ethylamine is an organic compound with the formula CH 3 CH 2 NH 2.This colourless gas has a strong ammonia-like odor.It condenses just below room temperature to a liquid miscible with virtually all solvents. It is a nucleophilic base, as is typical for amines.Ethylamine is widely used in chemical industry and organic synthesis.

The rate of formation is often pH dependent and proportional to the concentration of unprotonated amine (inversely related to the basicity of the amine) and to the concentration of N2O3, and hence to the square of the NO2 concentration. An optimum pH in the range of 2.5 to 3.3 is commonly observed for N-nitrosamine formation ...
The strong base determines the pH. Classify each of the following ions as acidic, basic, or neutral. 1. Sr 2. NO3 3. I 4. Cr 5. F 6. CN 7. NO2 8. Cl 9. SO4 10. C2H3O2 ...
