What Is the Source of Dr. Seuss Green Eggs and Ham

Many hair-coloring products react with the proteins in hair to produce a black-colored compound that covers the gray. [Pg.59]

Some hair-coloring products contain the water-soluble compound lead (II) acetate, Pb(CH3COO)2. When the coloring product is applied to the hair, a chemical reaction occurs between the Pb2+ ion and the sulfur atoms in cysteine and methionine incorporated in amino acids in hair proteins. The insoluble black product lead(II) sulfide forms. [Pg.59]

Thermal degradation of these amino acids yield such end products as hydrogen sulfide (H2S), ammonia (NH3), and methane (CH4), and organic acids such as acetic acid (CH3COOH) and formic acid (HCOOH). [Pg.60]

How Does Washing Soda Soften Hard Water [Pg.61]

The addition of washing soda to water has been recommended to accomplish a number of tasks, including softening hard water as well as improving the cleaning ability of a detergent. A simple chemical reaction contributes to the effectiveness of this substance. [Pg.61]
