what happens when metal react with dilute reaction
Answers
Answer:When a metal reacts with a dilute acid, a salt and hydrogen are formed.
Explanation:
When a metal reacts with a dilute acid, a salt and hydrogen are formed.
The more reactive the metal, the more rapid the reaction is. A metal below hydrogen in the reactivity series will not react with dilute acids.
For example, magnesium reacts rapidly with dilute hydrochloric acid:
magnesium + hydrochloric acid → magnesium chloride + hydrogen
Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g)
The salt magnesium chloride is dissolved in the water, so it has the state symbol (aq) meaning aqueous.
Answer:
Metals form respective salts when react with dilute acid. Reaction of sodium metal with dilute acid: Sodium metal gives sodium chloride and hydrogen gas when react with dilute hydrochloric acid. ... These do not react with water or dilute acids.
