Question

does normality measure concentration of solutions??

Answer 1

Yes, and in my opinion, which isn't worth much these days, normality is far superior in some situations to molarity. But the use of normality is being phased out (many schools no longer teach it) and before long it won't even be listed in a text. Pity. When I taught quantitative analysis years ago I never used anything BUT normality. We NEVER used molarity. Gravimetric factors also have been phased out. Too bad, also.
