Question

Why is concentrated sulphuric acid a weaker acid compared to dilut sulphuric acid?

Answer 1

Answer:

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

Answer 2

Answer:

Explanation:

The strength of an acid depends on the concentration of hydronium ions present. Due to the presence hgher amount of water in dilute sulphuric acid, it has a higher concentration of hydronium ions than concentrated sulphuric acid. Hence it is more acidic.
