What is an acid and how many ionizable hydrogens are present in sulphuric acid (H₂SO₄)?
Understand the Problem
The question is asking about the properties and definitions of acids, specifically focusing on what makes a substance an acid and the concept of ionization. It also references the number of ionizable hydrogens in certain acids, which indicates the question might be aiming for a comparison or explanation related to this concept.
Answer
Two ionizable hydrogens
Sulfuric acid (H₂SO₄) has two ionizable hydrogens.
Answer for screen readers
Sulfuric acid (H₂SO₄) has two ionizable hydrogens.
More Information
Sulfuric acid is a diprotic acid, meaning it can donate two protons (H⁺) through dissociation. The first dissociation produces one hydrogen ion and hydrogen sulfate (HSO₄⁻), and the second dissociation produces another hydrogen ion and sulfate (SO₄²⁻).
Tips
A common mistake is thinking all hydrogen atoms in an acid are ionizable, but only those that dissociate in water are considered ionizable.
