Asolution that contains equal number of hydrogen and hydroxyl ions would be called

Neutral solution

Neutral solution have equal number of hydrogen ions and hydroxyl ions in a solution. Its pH is naturally equal to 7 and the charge in that solution is neutral since the concentrations are equal. In the event that the concentration is unequal, the solution would have had a positive or negative charge.

Additionally, acidic solutions have more hydrogen ions than hydroxide ions while an alkaline solution contains more hydroxide ions than hydrogen ions.

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.
