Question

what happens when metals and non-metals react with acids respectively?

Answer 1

When metal reacts with dilute acid, respective salt and hydrogen gas are formed. But all metals do not react in the same manner and not produce salt and hydrogen gas. For example copper does not react with dilute acid.

Answer 2

hiii Acid is a very dangerous liquid because it is corrosive and it can 'eat away' almost anything. However when it reacts with some objects it produces some gas.

When acids react with metals, they produce a salt and hydrogen gas. Most metals react with acids, but not all. The general equation that describes the chemical reaction between an acid and metal is metal + acid = salt + hydrogen gas.

Example: Iron + hydrochloric acid =iron chloride and hydrogen gas (Fe + 2CHI = FeCI2 + H2)

To write a general word equation for the reaction of metals and acids you to present it like this :

metal + acid = salt (metal + acid i.e magnesium sulphate) + Hydrogen

If you put a lit splint in the gas produced when a metal reacts with an acid it burns with a squeaky pop, due to the hydrogen created.

Ans:Whenever acids react with metals they are accompanied by the displacement reaction in which metal replaces hydrogen which is isolated as H2 gas.Ultimately we get salt of anions in the acid along with hydrogen gas as our final products.This can be simply understood by the general reaction:

Metal+Acid ➡️Salt+Hydrogen gas

Eg:Metal with strong acid:-

Mg+2HNO3 ➡️Mg(NO3)2+H2⬆️



Eg:Metal with weak acid:-

Mg+2CH3COOH➡️ (CH3COO)2Mg+H2⬆️



There are certain metals which do not react with acids like:

Eg:Copper, Silver, Gold and Platinum

There are metals which rapidly react with acids like:

Eg:Calcium,Sodium and Potassium

Hence,we can say that the reactivity of metals play an important role with its reaction with acids under given set of conditions.

Assuming that a reaction is able to take place (not all metals will reacts with all acids), the typical result of the reaction between an acid and a metal is the formation of a salt.

For example, when sodium reacts with hydrochloric acid (HCl) the products will be sodium chloride and hydrogen. Similarly, the reaction between a metal and sulphuric will form a sulphate, between a metal and nitric acid, a nitrate and so on.
