Project Report on Caustic Soda

Caustic  soda, also known as sodium hydroxide (NaoH)  is  an important industrial chemical product produced on a tonnage basis in  both  solid and liquid form.  It is  deliquescent,  absorbing water  vapour  and  carbon  dioxide from the  air.   It  is  also extremely  corrosive  and  should be  handled  with  great  care. Adequate  protection  from body contact with the  solid  form  or concentrated  solutions  should be provided.  It is also  a  fire hazard  compound  as  it  heats  spontaneously  and  may   ignite combustible materials that are nearly. A large part of the huge amount used annually in the U.S. (About  21/2 million tons) is produced by the electrolysis of  the sodium chloride solutions in the electrolylic cells, such as  the Hooxer, Nelson, Force, or Allen-Moore.  Chlorine is a by  product of the reaction.  Alternative process is the soda-lime method.
