Question

1. A compond x is a Colourless and
odourless liquid having ph=7. Its
acidic solution undergoes decomposition
in presence of electricity to produce
gases y and z . The volume of y is
double than 2.y is highly combustibel
whereas z is supporter of
combustion. Identify t he and
write the chemical reactions
involved - Name the process.​

Answer 1

Answer:

That compound x is water (H2O)

and the gases that evolve is H2 & O

in ratio 2: 1

it is decomposition reaction or electrolytic decomposition rxn

Answer 2

Explanation:

The Compound X is H2O (Water).

• When Electric Current is passed through acidified water, it decomposes to give Hydrogen gas and Oxygen gas.

X -> Y + Z

it means,

2H2O -> 2H2 + O2

• Volume of Y is double than Z.

Y = Hydrogen Gas

(H2 is highly combustible)

Z = Oxygen Gas

(O2 Support Combustion)

• The name of the process is Electrolytic Decomposition or Electrolysis.

Hence,

X = H2O

Y = H2

Z = O2
