Answer : ammonium hydroxide ( NH4OH ) is base. Such is ammonium hydroxide; NH₃ + H₂O ⇄ NH₄⁺ + OH⁻ In the ionization of a weak base, the process results in an equilibrium reaction. Which of the following would change the colour of this pH paper to greenish-blue? a. it cannot hold on to its hydroxide ions. Assertion: Universal indicator gives green colour with distilled water. 21. c. it is completely ionized in aqueous solution. The liquid. An aqueous solution turns red litmus solution blue. It therefore, can't "dissociate to a slight extent," because there aren't any molecules of NH4OH to dissociate. b. it dissociates only slightly in water.
