What will happen when dilute sulphuric acid is added to a mixture of iron filings and sulphur powder heated to red hot followed by cooling?
b
.
When dilute sulphuric acid is added to a mixture of iron fillings and sulphur powder heated to red hot followed by cooling,
iron reacts with sulphur to form iron sulphide, FeS
. FeS formed reacts with sulphuric acid to form ferrous sulphate and release hydrogendisulphide gas.
What happens when dilute hydrochloric acid reacts with iron fillings give the balanced equation for the reaction taking place?
6HCl(aq) + Fe(s) → FeCl3(aq) + 3H2(g)
Which ion causes the acidity in dilute hydrochloric acid?

What happens on adding dilute sulphuric acid?
Sulphuric acid in dilute form behaves as an acid as
the protonation of water rapidly takes place
and forms hydronium ions.
Which substance does not react with HCl?
– Therefore the metals which do not react with dilute hydrochloric acid are
copper and mercury
.
Which equation for the reaction between sodium carbonate and dilute hydrochloric acid is correct?
When solutions of sodium carbonate and hydrochloric acid are mixed, the equation for the hypothetical double displacement reaction is:
Na2CO3 + 2 HCl → 2 NaCl + H2CO3 Bubbles
of a colorless gas are evolved when these solutions are mixed.
What happens when dilute hydrochloric acid is added to zinc granules?
Zinc reacts easily with the acid to produce hydrogen bubbles. … When dilute hydrochloric acid is added to granulated zinc placed in a test tube,
zinc metal is converted to zinc chloride and hydrogen gas is evolved
in the reaction. In the reaction we can see that a zinc chloride salt is formed and hydrogen gas is evolved.
What would you observe when dilute hydrochloric acid is added to a reactive metal write the balanced chemical equation for the reaction of iron and dilute Sulphuric acid?
Hydrogen gas is produced when dilute hydrochloric acid is added to a reactive metal. it forms iron sulphate and liberate hydrogen gas.
Fe + H

What do you observe when dilute sulphuric acid is added to iron sulphide?
When iron sulphide is added to dilute sulphuric acid, you will get
iron sulphate, water and sulphur dioxide
as the products.
What happens when dilute hydrochloric acid is added to sodium carbonate?
When dilute hydrochloric acid reacts with sodium carbonate, then
sodium chloride, carbon dioxide and water are formed
. A brisk effervescence is seen in the release of carbon dioxide.
When dilute sulphuric acid reacts with iron sulphide the gas evolved is?
When dilute sulphuric acid reacts with iron sulphide the gas evolved is
Hydrogen sulphide
.
Why does copper not react with dilute h2so4 and dilute HCl?
Copper is less reactive than hydrogen and is present below hydrogen in the reactivity series. Only a more reactive element can displace a less reactive one.
Copper cannot displace hydrogen from acids
like dilute HCl and sulphuric acid.
Which component of the mixture FeS reacts with dilute HCl and gives hydrogen gas?
Answer:
Iron
reacts with the dilute HCl and gives hydrogen gas.
What will happen when you apply heat to the reaction of HCl with rusty nails?
What happens when rust reacts with HCl? – Quora. When HCl encounters iron, whether it is oxidized iron (Fe2O3) or metallic iron (Fe), it wants to form ferrous chloride (FeCl2 or FeCl3). Therefore, when acid reacts with metal,
it tends to dissolve both the rust and the metal
, in order to form the ferrous chloride.
What oxidation half reaction happens when iron reacts with hydrochloric acid?
The chemical reaction between Iron and hydrochloric acid yields Hydrogen and Ferrous Chloride or Iron(II) Chloride according to the following equation
Fe (s) + 2HCl (aq) ====> FeCl2(aq) + H2 (g)
. Be careful. Hydrogen is flammable and explosive. If done at home using a small amount of Iron outside the house.
What happens when Sulphur reacts with hydrochloric acid Class 8?
You can react sulfur powder with hydrochloric acid (HCl) at room temperature. The reaction products will be
sulfur chloride and hydrogen gas
. Hope this helps answer your question.
What is dilute hydrochloric acid?
Dilute hydrochloric acid is often used in the extraction of basic substances from mixtures or in the removal of basic impurities. The dilute acid converts the
base such as ammonia
or an organic amine into water soluble chloride salt.
Which of these metals will not react with dilute acids?
Dilute acids generally react with reactive metals like magnesium, zinc, aluminium and iron. … As a result,
copper, silver and mercury
cannot react with the dilute acid as they won’t displace the hydrogen from non-metal anion. Hence, Option D is correct.
Which metal does not give hydrogen on treatment with dilute HCl?
The correct answer is
Silver
. The metal does not give H
2
on treatment with dilute HCL is Ag.
What ions are present in dilute sulfuric acid?
Dilute sulfuric acid contains water. The ions present in this mixture are
H
+
and OH
–
(from the water) and H
+
and SO
4
2 –
from the sulfuric acid
. The H
+
ions are attracted to the cathode and the two negative ions are attracted to the anode but it is the OH
–
ion which loses electrons.
Which is not dissolved by dilute HCl?
BaSO4
is not soluble in dil. HCl.
