The water molecules surround the negative ions and positive ions and pull them away into the solution. This process is called dissociation
The hydroxide ion (OH-) is the only negative ion present in an aqueous solution of an Arrhenius base.
The H3O ion in aqueous solution is known as the hydronium ion, which is formed when a water molecule accepts a proton (H) from another water molecule. This ion plays a crucial role in acid-base chemistry and is responsible for the acidic properties of aqueous solutions.
A sheath of water molecules around an ion in solution is known as a hydration shell. These water molecules are attracted to the ion through electrostatic interactions, forming a stable arrangement around the ion. This hydration shell helps to stabilize the ion in solution and influences its properties.
The ion that imparts a deep purple color to an aqueous solution is likely the permanganate ion (MnO4-). Permanganate solutions are a vivid purple color due to the absorption of light in the visible spectrum.
An aqueous solution of LiC2H3O2 is slightly basic. This is because the acetate ion (C2H3O2−) is the conjugate base of acetic acid, which is a weak acid. The presence of this ion makes the solution slightly basic.

Ammonium ion (NH4+) is typically found in aqueous solution when it is part of a soluble salt, such as ammonium chloride (NH4Cl). In this context, the NH4+ ion is dissolved in water, making it aqueous. However, NH4+ itself is not a standalone aqueous substance; it must be in solution with a counterion to be considered aqueous.

When an acid is placed in an aqueous solution, the dominant ion will be the hydronium ion (H3O+). This ion is formed when the acid donates a proton (H+) to water molecules, resulting in the formation of hydronium ions.
An aqueous solution of LiC2H3O2 is slightly basic. This is because the acetate ion (C2H3O2−) is the conjugate base of acetic acid, which is a weak acid. The presence of this ion makes the solution slightly basic.
ClO4 typically refers to the perchlorate ion, which is a polyatomic ion composed of one chlorine atom and four oxygen atoms. When ClO4 is dissolved in water, it forms an aqueous solution. In this solution, the ClO4 ion dissociates into its constituent ions, ClO4- (perchlorate) and H2O (water), allowing it to conduct electricity and participate in chemical reactions. Therefore, ClO4 can indeed be an aqueous solution.
OH- as the reaction below: NH3 + H20 = NH4+ OH-
pH is the negative log of the activity of the hydrogen ion in an aqueous solution. A powder is not a solution.
When an acid is placed in water, the hydronium ion (H3O^+) is formed.
