Prepare a 1% copper sulfate solution. To make this solution, weigh 1 gram of copper sulfate (CuSO4 ·5H2O), dissolve in a small amount of distilled water in a 100 ml volumetric flask and bring to volume. Label this as 1% copper sulfate solution.
The answer would be: Igneous Rocks
Answer: Option (a) is the correct answer.
Explanation:
A dissociation reaction is defined as the reaction in which a compound beaks down into two or more different parts.
For example, molecular formula of water is
and when it dissociates then it given hydrogen ion and hydroxide ion.
Therefore, dissociation reaction for water is as follows.

Thus, we can conclude that out of the given options
is the correct equation for the dissociation of water.
