Briefly explain how acids react with metals, metal oxides and salts with their respective
chemical equations
Answers
Answer:
1) REACTION OF METALS AND DILUTE ACID - DEFINITION
Metals above the copper in the reactivity series can react with dilute acids to form metal salts and hydrogen.The higher up the series the more vigorous the metals will react.
Example is potassium reacts with dilute hydrochloric acid to give potassium chloride and hydrogen gas.
2K+2HCl⟶2KCl+H
2) REACTIONS OF METALS WITH SOLUTIONS OF OTHER METAL SALTS - DEFINITION
Reactive metals can displace any metal less reactive than itself from the oxide, chloride or sulphate of the less reactive metal in solution or their molten state. If metal A displaces metal B from its solution, it is more reactive than B.
CHEMICAL PROPERTIES OF METAL - DEFINITION
Metals in chemical reactions forms positive ions , for example dissociation of HCl in water forms H
+
ion .
Metals always forms basic oxide and hydroxides on reaction with acid.
REACTION OF METALS WITH BASES - DEFINITION
Base+metals→ base/metals/salt +H
2
2NaOH+Zn→Na

ZnO
2
+H

Base only reacts with zinc and aluminium
REACTION OF NON-METALS WITH ACID - DEFINITION
Non metals reacts with acid to produce corresponding acids.For example if nitric acid reacts with sulfur ,sulphuric acid is formed.
REACTION OF NON-METALS WITH BASE - DEFINITION
Non-metals reacts with bases to form salt and water.
