Water ionizes into hydrogen ions and hydroxide ions. It has a value.?
Kw (:
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.
Does the pH scale indicate the consentration of hydrogen ions or hydroxide ions?
The pH scale indicates the concentration of hydrogen ions in a solution. A lower pH value indicates a higher concentration of hydrogen ions, while a higher pH value indicates a lower concentration of hydrogen ions.
What pH indicates that the most hydroxide ions are present?
The highest pH value in a group of such values indicates that the greatest concentration of hydroxide ions is present in the substance with the highest pH. This is true because a higher pH indicates a lower concentration of hydrogen ions, and the product of the molar concentrations of hydrogen and hydroxide ions must always be 10-14 at standard temperature and pressure in a mixture that is mostly water.
If there are more hydroxide particles than hydrogen particles what might the pH be?
If there are more hydroxide particles than hydrogen particles, the solution is basic with a pH above 7. The exact pH value would depend on the concentration of the hydroxide particles present in the solution.
When water ionizes it produces equal amounts of hydrogen and hydroxide ions which can re associate with each other?
When water ionizes, it produces hydronium (H3O+) and hydroxide (OH-) ions, not equal amounts of hydrogen and hydroxide ions. These ions can indeed reassociate to form water molecules through a reversible chemical reaction.

Has a pH value equal to 7?
A pH value of 7 indicates a neutral solution, where the concentration of hydrogen ions is equal to the concentration of hydroxide ions. This means that the solution is neither acidic nor basic.
How do you measure the PH value of hydrocarbon?
The pH value of hydrocarbons cannot be measured directly because they are not water-soluble. Since pH measures the acidity or basicity of a solution, it can only be measured in aqueous solutions. Hydrocarbons are nonpolar molecules and do not dissociate in water, so pH testing is not applicable to them.
What happens to rubidium chloride when added to water?
Rubidium is a large sized atom of alkali metals family and is highly reactive towards water when it is added in water Rubidium hydroxide is formed along with bubbles of hydrogen gas this hydroxide is strong alkali so pH value of water shows a change from 7 to 12 , 13 or 14.
What has a pH of 1 and completely ionizes in aqueous solution?
A strong acid, such as hydrochloric acid (HCl), has a pH of 1 and completely ionizes in aqueous solution, meaning all molecules dissociate into their constituent ions. This leads to a high concentration of hydrogen ions (H+) in the solution, resulting in the low pH value.
What is the ionic product for water expressed in Kw?
The ionic product for water is expressed as Kw, which is equal to 1.0 x 10^-14 at 25°C. This value represents the product of the concentrations of hydrogen ions (H+) and hydroxide ions (OH-) in pure water.
Why is water not alkaline at 60 degrees celsius when the OH value in water at 60 degrees is greater that the value at room temperature-PLEASE help ASAP?
The pH of water is determined by the balance between hydrogen ions (H+) and hydroxide ions (OH-). At 60 degrees Celsius, the increase in temperature causes more water molecules to ionize, leading to an increase in OH- ions. However, this does not necessarily mean that water will be alkaline, as the pH scale is logarithmic and influenced by the ratio of H+ to OH- ions. Therefore, even with a higher concentration of OH- ions, the pH of water at 60 degrees Celsius may still be neutral or slightly acidic.
