A neutral solution has an equal numbe of?
A neutral solution has an equal number or concentration of hydrogen and hydroxide ions. A neutral solution is one that has a pH of 7.0. Pure water is a neutral solution.
Why is deionized water not an entirely accurate description of pure water?
because water itself is in equilibrium H20 <---> OH- + H+ that is why the pH of water = 7 because the concentration of hydroxide and hydrogen ions are equal, making it neutral
How does the number of hydrogen ions compare to the number of hydroxide ions?
In pure water, at standard conditions, the number of hydrogen ions (H⁺) is equal to the number of hydroxide ions (OH⁻). This balance occurs due to the self-ionization of water molecules: H 2 O ⇌ H OH − H 2 O⇌H +OH − For every water molecule that dissociates, one hydrogen ion (H⁺) and one hydroxide ion (OH⁻) are produced. The concentration of hydrogen ions (H⁺) is often denoted as [H⁺], and the concentration of hydroxide ions (OH⁻) is denoted as [OH⁻]. In neutral water (pH 7), these concentrations are equal: [H+]=[H−]=10−7 mol/L [H+ ]=[OH− ]=10−7 mol/L This balance ensures that the solution remains neutral. However, in acidic solutions, the concentration of hydrogen ions (H⁺) is higher than that of hydroxide ions (OH⁻), while in basic solutions, the concentration of hydroxide ions (OH⁻) is higher than that of hydrogen ions (H⁺). The product of the hydrogen ion concentration and the hydroxide ion concentration is always 10−14 mol 2 / L210−14 mol2 /L2 at 25°C, known as the ion product of water.
Why is the pH value of pure water pH 7?
Because water is completely neutral, since it is HOH, which means equal number of hydrogen and hydroxide ions.
Express the hydroxide and hydronium ion concentrations in pure water at 25C?
[H3O+] = 1x10^-7 M = hydronium ion concentration[OH-] = 1x10^-7 M = hydroxide ion concnetration
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?
true
A neutral solution has an equal numbe of?
A neutral solution has an equal number or concentration of hydrogen and hydroxide ions. A neutral solution is one that has a pH of 7.0. Pure water is a neutral solution.
What is pH pure water (neutral)?
pure water is neutral with a pH of 7

Will the pH change when Na2HPO4 is added to water?
Adding NaOH will increase the pH of water, because NaOH is a base. At 25°C: pH < 7 is an acidic solution pH = 7 is a neutral solution pH > 7 is a basic solution
Is pure water is a solution?
Absolutely pure water is not even that. Water dissociates itself into dissolved hydroxide and hydrogen ions, the latter forming hydronium. It is thus a solution of both of these ions.

What is the appropriate justification of why pure water is neutral?
YES, because of equal amount of hydrogen and hydroxide ions in the solution.
Is OH- present in pure water?
its 7
Why is the pH value of pure water pH 7?
Because water is completely neutral, since it is HOH, which means equal number of hydrogen and hydroxide ions.
Express the hydroxide and hydronium ion concentrations in pure water at 25C?
