NaOH is a base, so it does dissociate into H+ ions, but OH- ions are more in number.
Next question (Table)
H+ concentration in Acids is high and bases is low.
Ph of Acids is equal to 6.9 or less while that of bases is equal to 7.1 or more
Litmus:
Blue litmus changes to red when put in an acidic solution
Red litmus changes to blue when put in a basic solution
Hope it helps!!
