I would appreciate some guidance in finding additional information. I plan to do a science fair project where I will dissolve just sodium carbonate (washing soda) in hot water to remove an olive oil stain from cotton fabric. No other detergents or laundry boosters will be added and the water is soft and the sodium carbonate will not have to worry with "neutralizing" the magnesium and calcium deposits, etc. I plan to use different amounts of the sodium carbonate to see if a larger amount will dissolve the stain faster. My dilemna is that per my research via the internet, science dictionaries and encyclopedias I could not get an explanaation on the chemical process. I do not have access to university libraries and the public library is limited in their science/chemistry information. Either none was offered or too advanced for my purposes. I have had some chemistry, but will not have a complete chemistry unit until next year in 10th grade. Per my research, several scenarios should occur: 1) the sodium carbonate should create an emulsion that will list the stain from the fabric; 2) this process is the result of hydrolysis; and 3) a mild saponification could occur and convert the stain into "soap." Your input and help would be greatly appreciated as where I could find the additional information. Thank you. --Scott
