Montmorillonite has a two-to-one layer structure, which means

  • A.the layers are arranged in pairs of two
  • B.there are two minerals present in the deposit
  • C.an octahedral sheet lies between two tetrahedral sheets
  • D.two octahedral sheets lie above one tetrahedral sheet

Answer: C

Weak bonding between the stacked units allows water and cations to enter the interlayer space. This is the source of the very large swelling that makes bentonite so useful and so awkward in turn. A few per cent of bentonite transforms a body's workability.
