Acidic And Basic Oxides

GeO and SiO are both acidic oxides that react with water to form acids, whereas others are either amphoteric or basic. So, the correct pair is GeO and SiO .

To find the equivalent weight of sulfuric acid (H₂SO₄) in a reaction where it donates 2 H⁺ ions, we use the formula for equivalent weight:

The molar mass of H₂SO₄ is calculated as:

Adding these gives the total molar mass of sulfuric acid:

For simplicity, we use the approximate molar mass as 98 g/mol.

In this reaction, sulfuric acid donates 2 H⁺ ions, so the n-factor is 2.

Plug these values into the formula:

Thus, the equivalent weight of sulfuric acid in this reaction is 49 g/equiv.

In the category of acids, they are typically classified based on their ability to dissociate in water and release hydrogen ions (H⁺). A strong acid is one that completely dissociates in solution, meaning it effectively releases all of its possible hydrogen ions.

Consider the options:

Of the options provided, Hydrochloric acid is the strong acid, known for its complete dissociation in aqueous solutions.
