Adding hydroxide ions to 2+ hexaaqua ions These have the form [M(H2O)6]2+. Their acidity is shown in the reaction of the hexaaqua ions with water molecules from the solution: They are acting as acids by donating hydrogen ions to water molecules in the solution.eaction of hydroxide ions with the hexaaqua ion Statistically, there is far more chance of a hydroxide ion hitting a hexaaqua metal ion than of hitting a hydrogen ion. There are far more hexaaqua ions present.
Report Abuse. D (and maybe B) An Arrhenius base dissociates in water to form hydroxide ions. As a rule, that mean it is either a compound that contain hydroxie (like NaOH), or the dissolved form will 'steal' a hydrogen atom away from water, leaving hydroxide behind. A = vinegar, an acid.
