Understanding the Properties of a 0.1 M NaOH(aq) Solution

In chemistry, solutions are mixtures of two or more substances where one substance is dissolved in another. Aqueous solutions, specifically, involve a substance dissolved in water. In this article, we will explore the properties of a 0.1 M NaOH(aq) solution, focusing on its ability to conduct electricity and its classification as an Arrhenius base or acid.

What is an Arrhenius Acid or Base?

The Arrhenius definition of an acid and a base was introduced by Swedish chemist Svante Arrhenius in the late 19th century. According to this definition, an acid is a substance that increases the concentration of hydrogen ions (H+) in a solution, while a base is a substance that increases the concentration of hydroxide ions (OH-) in a solution.

The Arrhenius Acid

An Arrhenius acid is a substance that donates H+ ions in a solution. Examples of Arrhenius acids include hydrochloric acid (HCl), sulfuric acid (H2SO4), and nitric acid (HNO3). These acids are known to increase the concentration of H+ ions in a solution, making the solution acidic.

The Arrhenius Base

An Arrhenius base, on the other hand, is a substance that donates OH- ions in a solution. Examples of Arrhenius bases include sodium hydroxide (NaOH), potassium hydroxide (KOH), and calcium hydroxide (Ca(OH)2). These bases are known to increase the concentration of OH- ions in a solution, making the solution basic.

The 0.1 M NaOH(aq) Solution

Now that we have a basic understanding of Arrhenius acids and bases, let's focus on the 0.1 M NaOH(aq) solution. A 0.1 M NaOH(aq) solution is a solution that contains 0.1 moles of sodium hydroxide (NaOH) dissolved in 1 liter of water.

Conductivity of the Solution

The 0.1 M NaOH(aq) solution is a strong electrolyte, meaning that it can conduct electricity. This is because the NaOH molecules dissociate into their constituent ions, Na+ and OH-, in the solution. The presence of these ions allows the solution to conduct electricity.

Arrhenius Classification

As we discussed earlier, an Arrhenius base is a substance that increases the concentration of OH- ions in a solution. Since the 0.1 M NaOH(aq) solution contains NaOH molecules that dissociate into Na+ and OH- ions, it can be classified as an Arrhenius base.

In conclusion, a 0.1 M NaOH(aq) solution is a strong electrolyte that can conduct electricity. It is also classified as an Arrhenius base due to its ability to increase the concentration of OH- ions in a solution. The solution contains NaOH molecules that dissociate into Na+ and OH- ions, making it a strong electrolyte.

Based on the discussion above, the correct answer to the question is:
