In neutralisation reactions H+ and OH- ions come from the dissociation of water, H2O, which is part of the solution.
Water dissociates in equilibrium, shown as:
H2O(l) <-> H+(aq) + OH-(aq)
The representation H2O H plus plus OH signifies the dissociation of water molecules into hydronium ions (H+) and hydroxide ions (OH-) in aqueous solution. This is the auto-ionization of water where some water molecules act as both acids (donating H+ ions) and bases (accepting H+ ions). The concentration of H+ and OH- ions in pure water is equal at 10^-7 M.
The pH of a neutral solution with equal concentrations of H+ and OH- ions is 7. This is because the concentration of H+ ions equals the concentration of OH- ions in a neutral solution, resulting in a pH of 7.
This is the definition of a base.
False - such a solution is considered "neutral"...neither acidic nor alkaline (basic).
Solutions with an equal concentration of H+ (hydrogen) ions and OH- (hydroxide) ions are considered as neutral. This is because the H+ and OH- ions will combine to form water (H2O), maintaining a balanced pH level of 7.

No, acids do. Bases produce OH- ions
H plus and OH negative are ions of hydrogen and hydroxide in their dissolved states. When a compound is broken down, it is broken down into it's ions, which will each have a charge.
An arrhenius acid is, by definition, a solution with a higher concentration of H+ ion than OH-.
The pH of a neutral solution with equal concentrations of H+ and OH- ions is 7. This is because the concentration of H+ ions equals the concentration of OH- ions in a neutral solution, resulting in a pH of 7.

A Neutral solution
False - such a solution is considered "neutral"...neither acidic nor alkaline (basic).
Solutions with an equal concentration of H+ (hydrogen) ions and OH- (hydroxide) ions are considered as neutral. This is because the H+ and OH- ions will combine to form water (H2O), maintaining a balanced pH level of 7.
Non-electrolytes, such as sugar or ethanol, do not produce H+ or OH- ions when dissolved in water because they do not dissociate into ions.
When a solution has more hydrogen ions it will be acidic.
In the reaction given, the spectator ions are the ions that do not participate in the actual chemical change. In this case, the Na⁺ ions remain unchanged on both sides of the equation, so they are the spectator ions. The OH⁻ and H⁺ ions combine to form water (H₂O), while the Cr species is also involved in the reaction, potentially forming a compound.
