It is a white solid ionic compound consisting of sodium cations Na + and hydroxide anions OH −.. Sodium hydroxide is a highly caustic base and alkali that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns.It is highly soluble in …This page looks at the extraction of copper from its ores

and conducts electricity and heat relatively well. Metals are typically ductile (can be drawn into wires) and malleable (they can be hammered into thin sheets). These properties are the result of the metallic bond between the ...Sodium hydroxide washing every process involved in the extraction of metals will be discussed step by step. The main aim of designing an extraction process is to minimize the cost and gather the purest form of the metal as much as possible. The conventional metal extraction processes will be discussed elaborately on this concept page. The simpler ...A metal (from Greek μέταλλον métallon
