sodium hydroxide
Noun: A strongly alkaline, caustic inorganic compound with the chemical formula NaOH. It is a white solid at room temperature, highly soluble in water, and is commonly known as lye or caustic soda. It is a fundamental chemical used in numerous industrial processes.
"Sodium hydroxide" is used as a mass noun. It refers to the specific chemical substance itself. * It is used in the manufacturing of products like soap, paper, and aluminum. * It is used as a cleaning agent or drain cleaner due to its ability to dissolve organic matter. * It is used in chemical laboratories as a common base for titrations and reactions. * It is used in water treatment processes. * Safety Note: Handling requires caution as it is corrosive and can cause severe chemical burns.
