Equivalent weight per liter of solution called normality
Or
equivalent weight soluble in 1 liter solution
How make 1 N NaOH solution ?
Molecular weight of NaOH = 40 gm
=40 X 1000 /1X 1000 = 40gm
40 gm NaOH dissolved in 1 liter water = 1N NaoH solution
How make 1N H2S04 solution ?
Normality = gram of soult X 1000 /
gram of equivalent weight of solut * volume of solution
equivalent weight = Molecular weight / acidity or basicity
H2SO4 = 98/2
= 49
1 = gram of solut X 1000
=49 X 1000
= 49
Gm convert into volume using formula
D = M/V
V = 49/1.92
= 25.5208
= 26 ml
