Is H2SO4 an acid or a base?
Strong Acids Strong Bases HCl (hydrochloric acid) HNO3 (nitric acid) HClO4 (perchloric acid) H2SO4 (sulfuric acid) NaOH (sodium hydroxide) KOH (potassium hydroxide) Ca(OH)2 (calcium hydroxide).
Why is H2SO4 acidic?
Why H2SO4 acts as an acid? H2SO4 acts as an acid because it dissociates into two ions on dissolving in an aqueous solution and liberates proton or H+ ion. Since H2SO4 releases H+ ions in an aqueous solution, it acts as an acid.
