Question

Versene, a chelating agent having chemical formula C2H4(C2H2Na)4.If each mole of this compound culd bind 1 mole of Ca 2+ ,then the rating of pure versene expressed as mg of CaCo3 bound per g of chelating agent.

Sanjeev Malik IIT BHU · Answer

molar mass of versene= 224 mass CaCO3

1 mole versene = i mole Ca²⁺ = 1 mole CaCO₃

i.e 224 gm versene corresponds to 100 gm CaCO3

so 1 gm versene = 100/224 gm CaCO3

= 100/224 * 1000 mg of CaCO3

=446.428 per mg CaCO3 = rating
