Fantastic news! We've Found the answer you've been seeking!

Question:

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.
