What is the composition of the bubbles observed when the crude methyl benzoate product is washed with sodium bicarbonate? hint: consider the acidity of the solution (some HCl will be present) and the reactions of sodium bicarbonate with acids.
how many milliliters of a .215 M NaOH solution are needed to completely neutralize 2.50 mL of a .825 M H2SO4 solution
Oxygen is more electronegative than nitrogen; fluorine is more electronegative than the other halogens. Fluoride is a stronger field ligand than the other halogens, but ammonia is a stronger field ligand than water. Why
I am given the 10 ml of .200M Fe(NO3)3 and .25 ml of .00200 KSCN and 14.75 ml of .500 M of HNO3. How do I figure out the initial concentration of FE3+ and SCN-.
