When the soluble material is largely on the suface ofan insoluble and is merely washed off by the solvent, the operation is calld? (a) decoction (b) percolation (cj elutriation or elution (d) dissolution

a--Decoction is a method of extraction by boiling herbal or plant material to dissolve the chemicals of the material, which may include stems, roots, bark and rhizomes. ... Decoction can be used to make herbal teas, leaf teas, coffees, tinctures and similar solutions
b--Rainfall seeps underground through a process called percolation, where water travels downwards through the tiny spaces between rocks and soil particles. The water eventually saturates the underlying rock much like water fills the tiny holes of a sponge. This helps to replenish aquifers under the ground.
c--elution - the process of extracting one material from another by washing with a solvent to remove adsorbed material from an adsorbent (as in washing of loaded ion-exchange resins to remove captured ions); used to obtain uranium ions.
d--Dissolution refers to a process by which dissolved components, i.e. solutes, form a solution in a solvent. In this process a solution of the gas, liquid or solid in the original solvent are formed. Dissolution is the cause of selective leaching or localized corrosion Dissolution has great importance in chemical processes whether it is natural or man-made. Dissolution testing is extensively applied in the pharmaceutical industry to prepare and formulate drug dosage and to develop quality control specifications for its manufacturing process. It also used in testing catalysts.
Metal alloys are the result of dissolution of one solid into another.
