How many moles of ion are present in 1 M solution of H2SO4?

A 1 M solution of H₂SO₄ means 1 mole of H₂SO₄ per liter.

Step 1: Ionization of H₂SO₄

H₂SO₄ → 2H⁺ + SO₄²⁻

So, 1 mole of H₂SO₄ produces:

• 2 moles of H⁺ ions
• 1 mole of SO₄²⁻ ions

Step 2: Total moles of ions

Total ions = 2 + 1 = 3 moles of ions

Final Answer:

3 moles of ions per liter

Important Note:

• This assumes complete ionization (ideal case)
• In reality, second ionization is partial, but for exams we take it as complete

Key Takeaway:

1 M H₂SO₄ gives 3 moles of ions (2H⁺ + SO₄²⁻) in solution.
