PHOTOCHEM Potassium Hydroxide per 500gm (05528-0500)

Potassium Hydroxide
CAS 1310-58-3
Other names: Caustic potash; potassa; potassium hydrate

 
Description: Potassium hydroxide is available as white lumps, pellets, sticks, or cake. Rapidly absorbs water vapor and carbon dioxide from the air, forming carbonate which changes its alkalinity. Aqueous solutions attack wool, leather, and some metals, such as aluminum, lead, tin, and zinc.
Precautions: Keep container closed except when in use; do not handle with bare hands; wash thoroughly after handling. The solid or liquid causes burns on contact with body tissues, often with deep ulceration and ultimate scarring, so avoid contact with eyes, face, neck, skin, or inhalation of the dust or mist. Wear eye, face, skin, and hand protection. Chemical safety goggles for the eyes and gloves (neoprene, rubber, or vinyl) for the hands should always be worn.
First Aid: In case of contact, immediately flush eyes or skin with plenty of water for at least 15 minutes. If a physician is not immediately available, wash eyes for another 15 minutes and skin for additional one to two hours. Get medical attention, especially an eye specialist for the eyes. Remove contaminated clothing and shoes, and wash before re-use. If taken internally, dilute the chemical by drinking large quantities of water or milk, followed by dilute vinegar or fruit juice to accomplish neutralization of the alkali. Do not induce vomiting.
Note: When making solutions, add compound slowly with agitation to the surface of the solution to avoid violent spattering. Hot water should not be used.
