Question: M 1 V 1 /n 1 =M 2 V 2 /n 2 M 1 = molarity of EDTA = 0.01M M 2 = molarity of

M1V1/n1 =M2V2/n2

M1= molarity of EDTA = 0.01M

M2= molarity of bottled water = ?

V1=volume of titre used =3.46

V2= volume of bottled water used = 40

N1=mole equivalence =1

N2 = mole equivalence = 1

Calculate the hardness of water

Express result in the form of Ca2+ ppm andCaCO3 ppm. Hardness is expressed as the equivalentamount of Ca2+ in molarity from titration.
