Which of the following is an example of hydrolysis?
a. because of a reaction with acid rain, sandstone develops black surface deposits.
b. because of a reaction with water, feldspar is changed into clay minerals.
c. because of a reaction with carbonic acid, limestone is dissolved.
d. because of a reaction with oxygen, iron changes into rust.

B. Because of a reaction with water, feldspar is changed into clay minerals.

Explanation:

Hydrolysis is defied as the chemical breakdown of a substance when it is made to react with water. The word hydro means water, and the word 'lysis' mean to break down.

Water seeps down into the ground and comes in contact with the feldspar contained in the granite and convert it into clay particles which weaken the rock.

A. Because of a reaction with acid rain, sandstone develops black surface deposits is an example of carbonation.

C. Because of a reaction with carbonic acid, limestone is dissolved is also an example of carbonation.

D. Because of a reaction with oxygen, iron changes into rust is an example of oxidation.
