In general, the more reactive the metal, the faster the reaction. However,
aluminium has a protective oxide layer
, so it reacts slowly with acids to begin with.

Yes..the protective oxide layer that forms on aluminium when the hydrochloric acid breaks down..and..then
the acid reacts with the metal
.
What happens when aluminium reacts with dilute sulphuric acid?

When aluminum Al is placed in hydrochloric acid HCl it produces hydrogen gas H2 and aluminum chloride AlCl3?
(Aluminum (Al), a group 3A (13) metal with an ionic charge of 3+, reacts with aqueous solution of hydrochloric acid, HCl, to give hydrogen, H2, gas and an aqueous solution of aluminum chloride, AlCl3. In this reaction,
aluminum displaces hydrogen in HCl
to form aluminum chloride, which is a salt.)
How do metals react with dilute hydrochloric acid?
When a metal reacts with dilute hydrochloric acid, it
forms a metal chloride salt and hydrogen gas
. For example, sodium reacts with dilute hydrochloric acid to form sodium chloride salt and hydrogen gas.
How does metal react with dilute acid?
When a metal reacts with dilute acid,
salts are formed
. During this reaction hydrogen gas is evolved. In other words, when a metal is added to dilute acids, salt and hydrogen gas are formed. Sulfate salts and chloride salts are formed when metals react with dilute sulfuric acid and hydrochloric acid.
What will happen when chemical equation of the reaction involved 3m a dilute hydrochloric acid is poured on Aluminium foil?
2Al+HCl→2AlCl3+3H2
.
What did you observe when hydrochloric acid is poured on Aluminium foil explain with a balanced chemical equation?
Aluminium reacts with dilute hydrochloric acid to give aluminum chloride and hydrogen gas. The balanced equation is
= 2Al(s) + 6HCl(aq) —–> 2AlCl3(aq) + 3H2(g)
.
Which two metals react very fast with dilute hydrochloric acid?
Dilute acids react with relatively reactive metals such as
magnesium, aluminium, zinc and iron
. The products of the reaction are a salt plus hydrogen gas. Here’s a good way to remember it: MASH (M+A→S+H). In general, the more reactive the metal, the faster the reaction.
What happens when hydrochloric acid is poured on a?
when hydrochloric acid poured on a copper plate then
the hydrochloric acid reacts copper metal to form copper chloride and release hydrogen gas
. when the gas is released and burning candle is brought near the gas the candle extinguishes with a pop sound which indicates the presence of hydrogen gas.
Why aluminium does not react with dilute acid?
When aluminium is placed in an acid it may initially appear not to react. This is because
a layer of aluminium oxide forms on the surface of the aluminium due to prior reaction with the air and acts as a protective barrier
. The acid must remove this layer before it is able to react with the aluminium underneath.
What happens when aluminium reacts with dilute sulphuric acid and conc sulphuric acid give equations?
Aluminium reacts with hot, concentrated sulphuric acid to
form aluminium sulphate with the evolution of sulphur dioxide gas
. Sulphuric acid acts an oxidising agent, and gets itself reduced to SO2. Only with the dilute acid, the metal liberates hydrogen gas.
When dilute HCL is added to zinc pieces in a test tube?
When dilute hydrochloric acid is added to zinc pieces taken in a test tube,
the zinc metal displaces the hydrogen from the acid and hydrogen gas comes out in the form of small bubbles
. Hydrogen gas gives a pop sound with glowing splinter. This is a displacement reaction.
What is the chemical equation for aluminum and hydrochloric acid react to form aluminum chloride and hydrogen gas?
Problem: Aluminum reacts with hydrochloric acid to produce aluminum chloride and hydrogen gas.
2 Al(s) + 6 HCl(aq) → 2 AlCl3(aq) + 3 H2(g)
What mass of H2(g) is produced from the reaction of 0.75 g Al(s) with excess hydrochloric acid?
When aluminum metal reacts with HCl AlCl3 and hydrogen gas are produced?
Explanation: Aluminium metal will react with dilute hydrochloric acid to produce
aqueous aluminium chloride, AlCl3
, and hydrogen gas, H2 .
When aluminum is placed in hydrochloric acid aluminum chloride and bubbles of hydrogen gas are produced what is the balanced equation for the reaction?
Question: Aluminum reacts with hydrochloric acid to produce aluminum chloride and hydrogen gas. What mass of hydrochloric acid reacts when 87.7 grams of aluminum dissolves? The equation is:
2Al+6HCl→2AlCl3+3H2 2 A l + 6 H C l → 2 A l C l 3 + 3 H 2 .
Which metal does react with dilute hydrochloric acid?
Certain metals like
Aluminium, magnesium and Zinc
are highly reactive and they produce hydrogen gas with hydrochloric acid.
Which metals do not react with dilute acids and why?
Iron is the metal highly reactive with dilute hydrochloric acid because it is more active than the hydrogen in the activity series. So, option C is incorrect. – Therefore the metals which do not react with dilute hydrochloric acid are
copper and mercury
.
What happens when a metal reacts with dilute HCl or dilute H2SO4 write the reaction when iron reacts with dilute H2SO4?
Answer:
hydrogen gas is evolved
when the dilute hydrochloric acid added to a reactive metal when iron reacts with dilute H2SO4 the evolution of gas is formed.
Which one of the following will not react with dilute hydrochloric acid?
Copper (Cu) and Mercury (Hg) metal
do not react with dilute HCl to produce H2 as it comes after hydrogen in the activity series so they can not replace hydrogen from hydrochloric acid. Hence option 1 is correct.
What happens when a reactive metal reacts with a dilute HCl?
Hydrogen gas is liberated
when dilute HCl is added to a reactive metal.
What salt is formed in the reaction of aluminum with hydrochloric acid?
Almost all reactions of hydrochloric acid and aluminum (or its compounds) result in the formation of
aluminum chloride (AlCl3)
. The salt dissolves well in organic solvents (nitrobenzene, dichloroethane, acetone) and water.
Which metal does not react with dilute Sulphuric acid?
Copper
is the only metal which does not react with dilute sulphuric acid.
Does sodium react with dilute hydrochloric acid?
When sodium reacts with dilute hydrochloric acid, then
sodium chloride is formed and hydrogen gas evolves
.
What happens when gold is kept in dilute hydrochloric acid?
Answer: While hydrochloric acid, by itself, will not react with or harm gold in any way, gold and other precious,
non-reactive metals can be dissolved by a mixture of hydrochloric acid and nitric acid
, in a three-to-one ratio by volume.
What happens when reactive metal reacts with dilute mineral acid?
Answer: Highly reactive metals react with dilute acids, water, and oxygen. Evidence of the reaction with a dilute acid is the
formation of hydrogen gas bubbles
. These reactions involve the transfer of electrons from the metal to the hydrogen atoms.
Why does Cu not react with HCl?
Copper is a less reactive metal, hence does not react with any acid. … But Cu does not react with HCl
because the reduction potential of Cu is higher than that of hydrogen
. Only metals which have their reduction potential less than that of hydrogen react with non – oxidising acids.
When metals react with acid it produces a gas that burns with pop sound?
Metals readily react with acid and produce
hydrogen gas
which burns with a pop sound.
Does gold dissolve in HCl?
Hydrochloric acid is a strong acid. …
The HCl will dissolve most of the material around the gold
, such as the quartz or iron stone that typically surround a natural gold nugget, and leave the gold unharmed.
