I would like to know a few balanced chemical equations.

First, combining Aluminum sulfate with Hydrochloric acid.

Second, the results of that reaction combined with enough sodium hydroxide to achieve a neutral ph of around 7.

I am using the acid to split an emulsion with these ingredients:

Ingredient % CAS No: Exposure Limits:
Severely hydrotreated mineral oil       45 - 65      64742-52-5 OSHA: 5mg/m3
Emulsifiers                           30 - 50                 68608-26-4
                                                                    67701-22-8
                                                                    68154-86-9
Polar additives                      1 - 5                     8019-28-2
                                                                      61788-66-7
Chlorinated paraffin (C16-20, less than 50% chlorine)                   5 - 15                    61788-76-9
Stabilizers and inhibitors:                                            1 - 5

Thanks

There will be no reaction between Aluminum sulfate and Hydrochloric. All  ions are soluble. After add NaOH, you will get a precipitate of aluminum hydroxide and some will be also complexed as aluminate.

Thanks for the info.

Does anyone have any other suggestions on how to get this emulsion to split? My goal is to reduce our disposal cost as it is near 90% water in the emulsion.

Thanks
