The carbonated water is an example of ________.

Question

Consider the dissociation equilibrium of the following weak acid: \[ \mathrm{HA \rightleftharpoons H^+(aq) + A^-(aq)} \] If the \(pK_a\) of the acid is \(4\), then the pH of a \(10\ \text{mM}\) HA solution is ________ (Nearest integer). (Given: The degree of dissociation can be neglected with respect to unity)

Answer 1

Step 1: Understanding the Concept:
A solution consists of a solute and a solvent. Carbonated water (soda water) is water in which carbon dioxide gas has been dissolved under pressure.
Step 3: Detailed Explanation:
In carbonated water, Carbon Dioxide (\(CO_2\)) is the solute and Water (\(H_2O\)) is the solvent.
Since \(CO_2\) is a gas and water is a liquid, it is classified as a "gas in liquid" type of solution.
Step 4: Final Answer:
Carbonated water is an example of a gas in liquid solution.
