What is titration

Use the titration formula. If the titrant and analyte have a 1:1 mole ratio, the formula is molarity (M) of the acid x volume (V) of the acid = molarity (M) of the base x volume (V) of the base. (Molarity is the concentration of a solution expressed as the number of moles of solute per litre of solution.)

Where,
1000 = factor relating mg to grams
W = mass of the sample
N = normality of titrant
V = volume of titrant
Eq.wt = equivalent weight of acid
