The process is continued with finer and finer grinding and polishing abrasives. The final layer is removed chemically by etching with an acid or some suitable agent. During fine grinding the specimen is held so that the new finer scratches are introduced at approximately right angles, to those resulting from its previous rough grinding operations.

Acid washing of sand is done to displace any cations ( K, Ca, Mg, Fe ions) off of the sand''s cation exchange sites. This is followed by rinsing with deionized water to get rid of the Cl.
The final step, however, nearly always involves nitric acid, either alone in solution or combined with another acid. Nitric acid, generally, is not aggressive to stainless steel, and it serves to speed optimum corrosion resistance—or passivation. A word of caution is appropriate for chemical cleaning and pickling:
With that step finished, place the sump pump in the remaining pool water. During the acidwashing process, it should always be on and pumping out the water. A prewash and scrub are recommended before starting with the acid, in order to remove as much gunk and material off the walls as possible, especially from algaestained pools.
Sand Preparation. All sand used in the following procedures must first be acidwashed and airdried. Using a toploading balance, weigh out three 30 g samples of sand into 250 mL beakers. Wash each twice with 100 mL of a M solution of H 2 SO 4. After two washings with acid, wash each sand sample four times with distilled water.

General description Silicon dioxide (SiO 2) exists in three crystalline forms, namely quartz, tridymite and reacts with hydrofluoric acid to form silicon tetrafluoride (SiF 4) and water. Silicates are formed on reacting SiO 2 with alkali melts. SiO 2 is the main component in glass, brick and concrete and also forms the insulator in silicon devices.
