Cleaning & Neutralizing Spills of Ammonia Solutions
This method was developed by Margaret-Ann Armour, Assistant Chair of the Chemistry Department of the University of Alberta.
Please note: Ammonia vapors can be very irritating. It may be necessary to use respiratory protection when cleaning up spills of ammonia solutions. Only individuals who have been trained and fit-tested by EHS in the past year and who have received approval from EHS and McCosh Health Center to use a respirator may use respiratory protection, such as self-contained breathing apparatus or air-purifying respirators. Contact James Boehlert at 258-7882 for more information.
The addition of hydrochloric acid yields ammonium chloride, as indicated in the following reaction:
NH4OH + HCl ==> NH4Cl + H2O
If you have any questions about the procedure or where to get the appropriate supplies, please contact James Boehlert at 258-7882.
