None of the above

Detailed explanation-1: -Yes, H+ ions can be found in all basic solutions. They are basic since hydrogen ions (H+) have a much lower concentration than hydroxide ions.
Detailed explanation-2: -At a temperature of 25°C, an acidic solution will have a hydroxide ion (OH-) concentration that is less than 1.0 x 10-7 M. And a basic solution will have a hydroxide ion (OH-) concentration that is greater than 1.0 x 10-7 M.
Detailed explanation-3: -The pOH scale is similar to the pH scale in that a pOH of 7 is indicative of a neutral solution. A basic solution has a pOH less than 7, while an acidic solution has a pOH of greater than 7.
Detailed explanation-4: -The hydroxide ion is most associated with bases, as OH-ion concentration is what makes a compound basic; therefore, if you add more OH-to a very basic solution, it will become more and more basic acccordingly. A common example of a base is potassium hydroxide KOH or NaOH, that is to say, sodium hydroxide..
Detailed explanation-5: -OH, or hydroxide, group. Metal hydroxides, such as LiOH, NaOH, KOH, and Ca(OH)2, are bases. Nonmetal hydroxides, such as hypochlorous acid (HOCl), are acids.
