Problem- A 50 mL volume of the solution with an initial pH of 6.5 was titrated with 0.01 M HCl and after the addition of 9.8 mL of titrant, the solution pH was 4.8. Find the concentrations of the acetate and phosphate species that were present in the initial solution
As much detail as feasible is really appreciated
Question- In the ammonium ion, the nitrogen atom has donated an electron. Would you expect the geometry of the ammonium ion (NH4-) to differ from the methane molecule. Why
Environmental engineers utilizes alkalinity as a measure of the capacity of carbonate buffering systems in water samples Alkalinity (mol/L)= [HCO3- ] + 2[CO32- ]+ [OH - ] + [H+]. Determine the alkalinity of a water sample that has a pH of 9.9,26.0..
