What is the solubility of ferrous gluconate in water?

Published in Ferrous Gluconate Solubility 2 mins read

Ferrous gluconate exhibits varying solubility in water, with its dissolution capacity significantly increasing as the water temperature rises.

Solubility of Ferrous Gluconate in Water

Ferrous gluconate, a commonly used iron supplement, demonstrates a notable dependency on temperature for its solubility in water. Understanding this characteristic is crucial for its preparation, formulation, and effectiveness.

Here's a breakdown of its solubility under different temperature conditions:

Temperature Condition Amount of Water Required for 1 Gram to Dissolve Solubility (approximate grams per 100 mL of water)
With slight heating Approximately 10 mL 10 grams
At 100 °C (Boiling) Approximately 1.3 mL 76.9 grams

Key Insights into Ferrous Gluconate Solubility:

  • Temperature Dependence: As evidenced, ferrous gluconate is considerably more soluble in hot water compared to water at lower, "slightly heated" temperatures. This means that to achieve a higher concentration solution, heating the water is highly effective.
  • Practical Implications: This property is important for various applications, including:
    • Pharmaceutical Formulations: Manufacturers often utilize heated water to ensure complete dissolution and uniform distribution of ferrous gluconate in liquid medications or syrups.
    • Dietary Supplements: For individuals preparing solutions from powdered ferrous gluconate, using warm or hot water can facilitate quicker and more thorough dissolution.
