* Always add acid to water. The addition of acid to water is an exothermic reaction. Use high
temperature (e.g., Pyrex®) glassware.
† Extremely exothermic, submerge mixing vessel in an ice bath. See adjacent box.

Preparing Sulfuric Acid Solution?
Always ADD ACID (AA) to water! A great amount of heat is liberated
when sulfuric acid is added to water. The temperature of the solution
will rise rapidly. In fact, the temperature may rise so fast that the
solution will boil and possibly spatter a strongly acidic solution.
Consider immersing your mixing vessel in a bucket of ice to control the
solution temperature. Always add the acid to water very slowly while
stirring continuously.

Safe Storage of Acids
Flinn/SciMatCo® Wooden Acid Cabinets are Ideal
for School Storerooms
Corrosive chemicals, such as strong acids and bases, must be isolated
from other chemicals to prevent accidental contact and hazardous reaction
conditions. The best way to isolate your corrosive chemicals is to store them
in an approved corrosive storage cabinet like the Flinn/SciMatCo® wooden
acid cabinet. Locked storage cabinets also provide security against theft and
vandalism.
Flinn/SciMatCo® wood acid cabinets are designed specifically for high
school chemical storerooms. Made from 9-ply, high-density plywood, Flinn acid
cabinets are guaranteed never to rust or corrode.
Flinn/SciMatCo® acid cabinets will provide long life and safe, secure storage
for all your corrosives. See pages 644–645 for more information.
