To prepare the titrant fo amonia nitrogen analysis an analyst weight out 1.20 grams of concentration 98% sulfuric acid and brings to 1000 ml in lab pure water. if the molecular weight is 98 calculate the normality of the solution this analyst has prepare.
One NEVER knows the normality of a solution unless the equation is known. I assume that you are titrating both H atoms of the H2SO4; therefore, the equivalent weight is 1/2 the molecular weight (or 49 g).
mass H2SO4 = 1.20 g x 0.98 = ?? g
??g/49 = # equivalents and since that is in 1 L, the is the normality.
