Question

Does NaOH solution contain H+ ? If yes, then how is it basic?

Answer 1

No it does not contain H+ it contains OH- ..n so it is basic

Answer 2

NaOHNaOH or sodium hydroxide is a strong base. In water, it dissociates as Na+Na+ & OH−OH− ions.

NaOH(s)−→−H2ONa+(aq)+OH−(aq)NaOH(s)→H2ONa(aq)++OH(aq)−

The release of OH−OH− ions in its aqueous solution is the reason for its basic nature.
