The blue-green coloration of a solution in the context of litmus paper turning blue when dipped into a basic solution is due to the interaction of the litmus dye with hydroxide ions (OH⁻) in the basic solution. The hydroxide ions react with the dye molecules, leading to a change in their electronic structure and, consequently, a change in the color of the dye. This transformation results in the blue-green color observed in the solution. The specific mechanism involves the acceptance of electrons by the dye from the hydroxide ions, causing the color change and indicating the presence of a base.

The reaction between a metal oxide and an acid typically involves an acid-base neutralization reaction. In this process, the metal oxide, which is a basic substance, reacts with an acid to form water and a salt. The metal oxide, acting as a base, accepts protons (H+) from the acid. The general equation for this reaction is:
Metal oxide (basic) + Acid → Salt + Water
For example, the reaction between calcium oxide (CaO) and hydrochloric acid (HCl) produces calcium chloride (CaCl₂) and water:
CaO(s) + 2HCl(aq) → CaCl₂(aq) + H₂O(l)
This reaction characterizes the neutralization of an acid by a basic metal oxide.

Oxides that are described as basic in nature are metal oxides. These oxides are formed by the combination of a metal with oxygen. Basic oxides typically exhibit properties of bases, as they can react with acids to form salts and water through acid-base neutralization reactions. Basic metal oxides often contain electropositive metal cations, which readily donate electrons or accept protons. Examples include sodium oxide (Na₂O) and calcium oxide (CaO). These oxides contribute to the alkaline character of solutions when dissolved in water, as they generate hydroxide ions (OH⁻) through interaction with water molecules.
The reaction between carbon dioxide (CO₂) and calcium hydroxide (Ca(OH)₂) results in the formation of calcium carbonate (CaCO₃). This reaction is a type of acid-base neutralization, where carbon dioxide, acting as a weak acid, reacts with the strong base calcium hydroxide. The chemical equation is:Read more
The reaction between carbon dioxide (CO₂) and calcium hydroxide (Ca(OH)₂) results in the formation of calcium carbonate (CaCO₃). This reaction is a type of acid-base neutralization, where carbon dioxide, acting as a weak acid, reacts with the strong base calcium hydroxide. The chemical equation is:
CO₂(g) + Ca(OH)₂(aq) → CaCO₃(s) + H₂O(l)
Carbon dioxide dissolves in water to form carbonic acid (H₂CO₃), which then reacts with calcium hydroxide to produce the insoluble calcium carbonate. This reaction is utilized in various applications, such as carbon capture and in the treatment of flue gases in industries.

Nonmetallic oxides, often referred to as acidic oxides, tend to exhibit acidic behavior. These oxides result from the combination of nonmetals with oxygen. In the presence of water, they form acidic solutions by producing acids through reactions. For example, sulfur dioxide (SO₂) and nitrogen dioxide (NO₂) dissolve in water to form sulfurous acid (H₂SO₃) and nitric acid (HNO₃), respectively. These oxides can also react with bases to produce salts and water. Unlike basic metal oxides, nonmetallic oxides contribute to the acidity of solutions and are crucial in understanding environmental phenomena like acid rain.
The nature of nonmetallic oxides can be concluded to be acidic based on their reactions with bases. When nonmetallic oxides, such as sulfur dioxide (SO₂) or nitrogen dioxide (NO₂), react with bases, they form salts and water.

The nature of nonmetallic oxides can be concluded to be acidic based on their reactions with bases. When nonmetallic oxides, such as sulfur dioxide (SO₂) or nitrogen dioxide (NO₂), react with bases, they form salts and water. The chemical equations for these reactions illustrate the acidic behavior:

NO₂(g) + 2KOH(aq) → KNO₂(aq) + H₂O(l)
These reactions confirm that nonmetallic oxides act as acids, producing salts through acid-base neutralization reactions when in contact with bases.

For example, when zinc reacts with hydrochloric acid, zinc chloride is formed, and hydrogen gas is evolved:
Zn(s) + 2HCl(aq) → ZnCl₂(aq) + H₂(g)
The effervescence or bubbling observed during such reactions is due to the release of hydrogen gas.

Metals high up in the reactivity series, such as aluminum, magnesium, and calcium, cannot be obtained from their compounds by heating with carbon due to thermodynamic considerations. These metals have a strong affinity for oxygen, and their oxides are thermodynamically more stable than the corresponding carbonates or sulfides. When heated with carbon, these metals’ oxides are not effectively reduced, and the carbon reduction process is insufficient to overcome the thermodynamic stability of the metal oxides. Therefore, alternative methods, such as electrolysis or more reactive reducing agents, are required to extract metals high in the reactivity series from their compounds.
