Questions

  1. How to prepare 0.5M AlF3?

    1 answer
    1. This product is not tested for solubility but is reportedly slightly soluble in water. The SDS suggests 5.3 mg/L. This is much lower than the desired 0.5 M. Other sources show a higher solubility in water as the PubChem information demonstrates. It would appear that 0.5 M may be far beyond the limitations of solubility for this product.

      https://pubchem.ncbi.nlm.nih.gov/compound/Aluminum-fluoride#section=Solubility
      0.559 g/100 mL or 5.59 g/L = about 66 mM.
