Application

D-Gluconic acid is a non-volatile, organic acid generally used as a sequestering agent and as a scale inhibitor.[1] Due to its tendency to chelate with earth alkaline elements and heavy metals, it is also used as a metal extractant.[1] Gluconic acid and its salts are
used in hygienic products, food and pharmaceutical industry.[2]

Questions

  1. Hi what is the molarity of the solution provided? 25g in 50%wt solution

    1 answer

    1. At exactly 50% the molarity of this solution is 3.14M. The molarity may be calculated using the following equation below:

      Molarity (moles/L) = Density (g/L) ÷ Molecular Weight (g/mol) * purity
      = 1234g/L ÷ 196.16 g/mol * 0.50
      = 3.14539M

      The concentration of this product ranges from 49 - 53% and may change slightly from lot to lot. Please see the link below to access a sample or specific lot Certificate of Analysis:
