Instructor's Notes

1.0

Caustics

Caustics are materials with pH > 10. Examples include

ammonium hydroxide, calcium hydroxide, and sodium

hydroxide.

1.1

Separate from acids.

1.2

Store solutions of inorganic hydroxides in polyethylene

containers.

1.3

Store large containers below eye level.

2.0

Acids

Acids are materials with pH < 5. Examples include acetic,

chromic, and hydrofluoric.

2.1

Separate from bases and materials that could evolve

toxic vapors on contact (i.e., sodium cyanide).

2.2

Store large bottles low to the ground -- at least below

eye level.

2.3

Separate inorganic acids from organic acids (i.e., acetic,

oxalic, etc.).

2.4
