Cation exchange capacity of a clay measures

  • A.the plasticity index measured on the wet clay
  • B.the quantity of exchangeable cations it can hold
  • C.the total silica content present in the mineral
  • D.the temperature at which it finally dehydroxylates

Answer: B

Substitution within the lattice leaves a net negative charge that is balanced by cations held at the surface and in the interlayer. Those cations can be exchanged, which is what deflocculation of a casting slip actually exploits.
