Question

Why is the concentrated sulphuric acid is weaker acid compared to dilute sulphuric acid?

• A. Less presence of $O{H}^{-}$
• B. Easily gives $H^{+}$
• C. Less presence of $H^{+}$
• D. All of the above

Answer 1

Answer: (C)

Less presence of $H^{+}$

Concentrated sulfuric acid does not dissociate completely in the aqueous solution to give ions and does not conduct electrical conductivity while dilute sulfuric acid dissociate 100% to give hydronium ions in the solution and has more acidity.
