Under standard conditions, potassium bromide is a white crystalline powder. It is freely soluble in water; it is not soluble in acetonitrile. In a dilute aqueous solution, potassium bromide tastes sweet, at higher concentrations it tastes bitter, and tastes salty when the concentration is even higher. These effects are mainly due to the properties of the potassium ion—sodium bromide tastes salty at any concentration. In high concentration, potassium bromide strongly irritates the gastric mucous membrane, causing nausea and sometimes vomiting (a typical effect of all soluble potassium salts).
Benzoyl peroxide (BPO) is a medication and industrial chemical. As a medication it is used to treat mild to moderate acne. For more severe cases it may be used together with other treatments. Some versions come mixed with antibiotics such as clindamycin. Other uses include bleaching flour, hair bleaching, teeth whitening, and textile bleaching. It is also used in the plastic industry. Common side effects are skin irritation, dryness, or peeling. Use in pregnancy is of unclear safety. Benzoyl peroxide is in the peroxide family of chemicals. When used for acne it works by killing bacteria.
