Assertion (A): Thinning a flocculated slip by adding water is the wrong remedy.
Reason (R): It lowers the solids content without correcting the state of dispersion.

  • A.A is false but R is true
  • B.Both A and R are true, and R is the correct explanation of A
  • C.Both A and R are true, but R is not the correct explanation of A
  • D.A is true but R is false

Answer: B

Both are true and the reason gives the objection: the slip becomes more fluid but casts even more slowly and shrinks more on drying, so the underlying dispersion problem has to be addressed instead. Water dilutes the slip without dispersing anything.
