    Mam At 7:10
    Equivalent weight of mgcl2 might be
    10*50/47.5 = 10.5263 mg/litre
    Is this correct??
    Btw awesome explanation...

    • @dr.nishasingh
      @dr.nishasingh  Год назад +8

      Yes it should be 47.5

  • @Saiyanism031
    @Saiyanism031 4 года назад +1

    Mam but in the book, its mentioned that the formula of (equivalent of CaCO3) is = (Amount of hardness producing salt x Molecular weight of CaCO3)/ Molecular weight of hardness producing salt .
    And not equivalent weight

    • @Saiyanism031
      @Saiyanism031 4 года назад +1

      Instead of using molecular weight you are telling us to use equivalent weight

    • @dr.nishasingh
      @dr.nishasingh  4 года назад +1

      Yes because molecule weight is not applicable for all salts and ions.

    Is eq. wt. of MgCl2 is correct?

    • @dr.nishasingh
      @dr.nishasingh  3 года назад +4

      So sorry! It should be 47.5.
      55.5 is the equivalent weight of CaCl2.
