Can silica affect cation conductivity
WebThe released hydrogen ions can create an acidic solution – that’s why cation conductivity is sometimes called acid conductivity or Conductivity after Cation Exchange (CACE). … WebIons can have one charge or more, the most usual range being 1 to 3. Ions can be made of one atom only, or several atoms linked permanently together, like molecules. Examples: • A monovalent atomic cation: the sodium ion Na+ • A divalent atomic cation: the calcium ion Ca++ • A monovalent molecular cation: the ammonium ion NH4 +
