18/4/2018· its conductivity. Impurities that can dissolve in water and conduct electricity include acids, bases, and salts. These substances are known as electrolytes, further classified as either weak or strong, which describes their relative electrolytic strength.
Metals and Non-Metals - CBSEGuess
Metals like aluminium, zinc, iron do not react with hot/cold water ; they react only with steam to form a metal oxide and hydrogen . 2Al + 3 H 2 O → Al 2 O 3 + 3H 2 Zn + H 2 O → ZnO + H 2 3Fe + 4H 2 O → Fe 2 O 3 + 4H 2 Metals like lead, copper, silver
Metal It has been suggested that Properties and uses of metals be merged into this article or section. (Discuss) In chemistry, a metal (Greek: Metallon) In chemistry, the term ''base metal'' is used informally to refer to a metal that oxidizes or corrodes relatively easily, and reacts variably with dilute hydrochloric acid (HCl) to form hydrogen.
