What are solutions that have an equal concentration of H plus ions and OH ions considered as?
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.
Is it true that solutions that have an equal concentration of H plus ions and OH- are considered acidic?
False - such a solution is considered "neutral"...neither acidic nor alkaline (basic).
What makes a solution acidic or alkaline?
Acidic solutions have a higher concentration of hydrogen ions (H^(+)) and a low concentration of hydroxide ions (OH^(-)). Alkaline solutions have a higher concentration of hydroxide ions (OH^(-)) and a low concentration of hydrogen ions(H^(+)). Water at pH = 7 has equal amounts of hydrogen ions and alkaline ions. It naturally dissociates as H2O(l) < ====-> H^(+) + OH^(-).
Is 9 the pH of equal numbers of hydronium ions and hydroxide ions?
No. pH is the negative logarithm of the concentration of the hydronium ion. Equal numbers of hydronium ions and hydroxyl ions occurrs only when a solution is neutral.
Is it true that a substance with equal numbers of H ions and OH- ions is a basic solution?
No, a substance with equal numbers of H+ ions and OH- ions is not necessarily a basic solution. In fact, a solution with equal concentrations of H+ and OH- ions is considered neutral, with a pH of 7. Basic solutions have a higher concentration of OH- ions compared to H+ ions, resulting in a pH greater than 7.

Solutions with a pH higher than 7.0 are?
considered basic or alkaline. These solutions have a lower concentration of hydrogen ions and a higher concentration of hydroxide ions. Common examples include soap, ammonia, and baking soda.
What is the pH of pure H2O?
The pH of pure H2O is 7, which is considered neutral. This means that the concentration of hydrogen ions is equal to the concentration of hydroxide ions.
What does the pH if a solution depend on?
the concentration of OH ions in solutions
What is the pH of H2O?
The pH of pure water is typically around 7, which is considered neutral. This means that the concentration of hydrogen ions (H+) is equal to the concentration of hydroxide ions (OH-) in the water.
What pH value id neutral?
A pH value of 7 is considered neutral. At this pH, the concentration of hydrogen ions (H+) is equal to the concentration of hydroxide ions (OH-), resulting in a balanced solution.
Do basic solutions contain hydronium (H3O )IONS?
Basic solutions do not contain hydronium ions (H₃O⁺) in significant concentrations; rather, they have a higher concentration of hydroxide ions (OH⁻). In fact, when a base dissolves in water, it typically reduces the concentration of hydronium ions, leading to a higher pH. While H₃O⁺ ions are always present in water, their concentration decreases in basic solutions compared to neutral or acidic solutions.
What happens to the pH if the concentration of H3O and OH- are the same?
If the concentration of H3O+ and OH- ions are equal, the solution is neutral with a pH of 7. This is because in neutral water, the concentration of H3O+ ions (from dissociation of water) is equal to the concentration of OH- ions.
