    I think lime water is used in clarks method instead of slaked lime because we use aqueous solution of calcium hydroxide which is like water …can you explain?

      First to correct you, the clarks method does not depend upon any physical appearance. Secondly the compound calcium hydroxide used in the mentioned reaction is saturated plus solid. Hence slaked lime is preferred in clarks method.
