Contaminants and Impurities in Salts

    Cards (6)

    • What are contaminants?
      Substances that shouldn't be in salt
    • What distinguishes contaminants from impurities?
      • Contaminants:
      • Origin: External sources
      • Presence: Unintentional
      • Effect: Lower salt purity
      • Impurities:
      • Origin: Naturally part of salt
      • Presence: Occur naturally
      • Effect: Lower salt quality
    • What happens to salt crystals when contaminants are present?
      They grow slower and have irregular shapes
    • What is one effect of contaminants on crystal purity?
      Contaminants can become included in crystals
    • How do impurities affect crystal formation?
      They disrupt the arrangement of ions
    • What are the effects of contaminants and impurities on salt crystals?
      • Contaminants:
      • Source: External
      • Effect: Slows growth; crystals become smaller
      • Impurities:
      • Source: Natural to salt
      • Effect: Slows growth; crystals become smaller
