The concentration of hydrogen ions determines the pH. Since water is neutral with a pH of 7 or so, any substance with a lower concentration is acidic.

Lower concentrations of H plus ions than pure water basic acidic or polarity?

Lower concentrations of H+ ions indicate a basic solution. Pure water has a neutral pH, so any solution with a lower concentration of H+ ions than pure water would be considered basic. Acidity increases as the concentration of H+ ions in a solution increases.


Which is not a way to express the hydroxide and hydronium ion concentrations in pure water at 25 C?

In pure water at 25°C, the concentrations of hydroxide ions (OH⁻) and hydronium ions (H₃O⁺) are typically expressed in terms of molarity (M) or pH. A way that is not used to express these concentrations is by using mass percent, as this method is more applicable to solutions with solutes rather than to ion concentrations in pure water.


How does an acidic solution differ from pure water?

An acidic solution has a lower pH value (below 7) compared to pure water which has a neutral pH of 7. Acids in the solution will increase the concentration of hydrogen ions (H+) and decrease the concentration of hydroxide ions (OH-), resulting in a more corrosive and sour taste.


A solution containing concentrations of H plus ions higher than pure water are called what?

acids


Which is not a way to express the hydroxide and hydronium ion concentrations in pure water at 25 and degC?

In pure water at 25°C, the concentrations of hydroxide ions (OH⁻) and hydronium ions (H₃O⁺) are typically expressed in moles per liter (M). An incorrect way to express these concentrations would be in terms of mass (e.g., grams per liter), as this does not directly relate to the molarity of the ions present in the solution.


What would be the pH of solutions that have H ions greater than pure water?

The pH of a solution is a measure of the concentration of hydrogen ions (H+) in the solution. Pure water has a pH of 7, indicating a neutral solution with equal concentrations of H+ and OH- ions. If a solution has a higher concentration of H+ ions than pure water, its pH would be less than 7, making it acidic. The lower the pH value, the higher the acidity of the solution.


Which is not a way to express the hydroxide and hydronium ion concentrations in pure water at 25 Celsius?

Using the terms "pOH and pH" is not a way to express the hydroxide and hydronium ion concentrations in pure water at 25 degrees Celsius. At 25 degrees Celsius, the concentrations of hydroxide and hydronium ions in pure water are equal: 1.0 x 10^-7 M.


The reason pure water has a pH of 7 is that there is the same concentration of hydrogen and hydroxide ions on the self-ionization of water?

Pure water has a pH of 7 because it is neutral, with equal concentrations of hydrogen ions (H+) and hydroxide ions (OH-) due to the self-ionization of water. This balance of ions gives rise to a pH level of 7, indicating a neutral solution.


Why is the pH value of pure water pH 7?

The pH value of pure water is 7 because it is neutral, meaning it has an equal concentration of hydrogen ions (H+) and hydroxide ions (OH-). In pure water, the self-ionization process creates an equilibrium where the concentrations of H+ and OH- ions are equal, resulting in a neutral pH of 7.


What is the ratio of H plus and OH ions in pure water?

In pure water, the ratio of H+ ions to OH- ions is 1:1, resulting in a neutral pH of 7. This is due to the self-ionization of water, where water molecules can donate and accept protons to maintain this balance.


What solution contains equal concentration or hydrogen and hydroxide ions?

Best example : water! H2O...it is H1OH1


What Pure liquid water has a pH of 7 which means that water is .?

Pure liquid water has a pH of 7, indicating it is neutral, meaning it is neither acidic nor basic. This neutrality arises because the concentrations of hydrogen ions (H⁺) and hydroxide ions (OH⁻) in pure water are equal. A pH of 7 serves as a reference point for measuring the acidity or alkalinity of other solutions.
