Solutions

Expert Solution

This is an ACIDIC buffer, which may turn basic if Enough base is added

thereofre:

Mercury Spill Kit - This is only for Hg/Mercury containing material, do not use

Base Compatible Aqueous Waste - Avoid this, we have an acidic buffer, there will be reaction

Acid Compatible Mercury Waste - Not likely, since this must contain mercury

Sanitary Sewer - Avoid this, since this is acidic

Acid Compatible Organic Waste - Not organic material

Acid Compatible Acutely Hazardous Waste - USE THIS, since it is hazardous due to low pH

Acid Compatible Aqueous Waste - This will also work fine, you could USE THIS as well

Concentrated Nitric Acid Waste - FAlse, no nitric acid used

Base Compatible Mercury Waste - Avoid this, no mercury containing materials

Organic Solid Waste - Not solid or organic

Base Compatible Acutely Hazardous Waste - Not basic

Inorganic Solid Waste - Not solid

Base Compatible Organic Waste - Not organic
