How is the pH determined?
By the concentration of hydrogen and/or hydroxide ions. For example, water (H2O) has an equal concentration of hydrogen and hydroxide ions. Hence, it is neutral (pH 7).
What is true of the hydroxide and hydrogen ions in a solution of pH 7?
At pH 7, the concentration of hydroxide and hydrogen (hydronium) ions is equal; both concentrations are equal to 10-7 mol/L.
Does the pH scale indicate the consentration of hydrogen ions or hydroxide ions?
pH stands for power of hydrogen and indicates concentration of Hydrogen ions. pOH indicates concentration of hydroxide ions.
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 the concentration of hydrogen or hydroxide ions in blood plasma or cell cytoplasm critical?
The concentration of hydrogen or hydroxide ions in blood plasma and cell cytoplasm is critical. These hydrogen and hydroxide ions can be combined to form water.
What solution contains equal concentration or hydrogen and hydroxide ions?
Best example : water! H2O...it is H1OH1
How is the concentration of hydrogen ions and hydroxide ions related in aqueous solutions?
Hydrogen ions: pH under 7.Hydroxide ions: pH over 7.
What is the PH of a solution in which the concentration of hydroxide ions is greater than the concentration of hydrogen ions?
< 7
Is it true that The pH scale measures the concentration of hydroxide ions?
No, pH measures the concentration of hydrogen ions. pOH would measure hydroxide concentration.
Why is pure water neutral despite the fact the production of hydrogen ions and hydroxide ions?
Because the number of positive hydrogen ions produced is equal to the number of negative ions produced, water is neutral. Water is neutral despite the production of hydrogen ions and hydroxide ions because the number of positive hydrogen ions produced is equal to the number of negative ions produced, water is 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.
What would happen to the concentration of hydrogen ions in a solution of a strong acid if an equal number of hydroxide ions were added to the solution?
It produces a neutral salt along with water
