Question

(a) Aluminium hydroxide reacts with sulphuric acid to form aluminium sulphate and water. Write a balanced equation for this reaction.
(b) Balance the following chemical equation
MnO2 + HCl → MnCl2 + Cl2 + H2O

Answer 1

(a) Balanced chemical reaction:

$\bold{2 A l(O H)_{3(a q)}+3 H_{2} S O_{4(a q)} \rightarrow A l_{2}\left(S O_{4}\right)_{3(a q)}+6 H_{2} O_{(l)}}$

• Aluminium sulphate formed is a salt which is dissolved in water and formed as aqueous solution in this reaction.
• Aluminium sulphate is the major product in this reaction.
• It is used in purification of water and in deodorants.

(b) Balanced chemical reaction:

$\bold{M n O_{2}+4 H C l \rightarrow M n C l_{2}+C l_{2}+2 H_{2} O}$

• Manganese dioxide reacts with hydrogen chloride gas to form manganese chloride with chloride gas and water.
• The manganese chloride is the major product in this reaction.
• This compound is used in manufacturing of dry cell batteries.

Answer 2

Balanced Reaction is Reactants Equals Products

Explanation:

$2Al(OH)_3 + 3H_2SO_4 --> Al_2(SO_4)_3 + 6H_2O$

• Aluminium along with hydroxide becomes a base as hydroxide, on linking with any metal becomes basic in nature.  

So reaction of an acid with base will give salt and water as a result.  

This is being given a name called Neutralization reaction.

So, Salt of sulphate is formed with $H_2O$

b.) The Balanced Equation for the given Reaction is -

$MnO_2 + 4HCl --> MnCl_2 + Cl_2 + 2H_2O$

Manganese Dioxide + Hydrochloric Acid gives Manganese Chloride + Chloride gas and Water
