"pH" is a convention used as a convenience. It indicates how acidic (or basic, that is, alkaline) a solution is. It is the negative logarithm of the hydrogen ion concentration, usually the latter is expressed in moles (or millimoles) per liter. Moles per liter is, of course, what we call "molarity." pOH is used in the same way, indicating the concentration of hydroxyl ions.

Generally,

Concentration of hydrogen ions + the concentration of hydroxyl ions = 10-14

A neutral solution has equal numbers of H+ and OH-

What is the oxidation number of oxygen in hydroxide?

Oxygen in hydroxide has the oxidation number -2. This combines with the oxidation number +1 of hydrogen to form an anion with net charge of -1.


What are the oxidation numbers of hydroxide?

The oxidation number of oxygen in hydroxide (OH-) is -2 since oxygen typically has an oxidation number of -2 in compounds. The oxidation number of hydrogen in hydroxide is +1 since hydrogen usually has an oxidation number of +1 when bonded to nonmetals like oxygen.


Why is water considered to be a neutral?

Because the number of hydrogen ions are the same as the number of Hydroxide ions.


A neutral solution has an equal numbe of?

A neutral solution has an equal number of hydronium ions (H3O+) and hydroxide ions (OH-) present, resulting in a balanced pH of 7. This equilibrium reflects the concentration of hydrogen ions being equal to the concentration of hydroxide ions in the solution.


What is the number of Hydrogen ions in 5.18 g of strontium hydroxide?

Strontium hydroxide is Sr(OH)2, with a molar mass of 121.6g/mol. If you have 5.18g of it, you have 5.18/121.6=0.0426mol of it. Multiply this by Avogadro's number to get 2.56x1022 representative particles of strontium hydroxide. Assuming you mean hydroxide ions instead of hydrogen ions, it's 2 hydroxide ions per formula unit, so double it to get 5.12x1022 hydroxide ions.


What is it when The number of moles of hydrogen ions equals the number of moles of hydroxide ions?

A neutral solution of about 7 pH.


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 is pH pure water (neutral)?

pure water is neutral with a pH of 7


What will be the number of hydrogen and hydroxide in a PH of 6?

In a solution with a pH of 6, the concentration of hydrogen ions (H+) will be 10^-6 moles per liter. The concentration of hydroxide ions (OH-) in water is 10^-14 moles per liter at 25°C, so in a neutral solution, there would be the same number of hydroxide ions.


What is the number of atoms in cupric hydroxide?

5 atoms = 1 Copper + 2 Hydrogen + 2 Oxygen


What solutions have a greater number of hydroxide ions than hydrogen ions?

An acidic solution has a greater number of hydrogen ions than hydroxide ions. However, technically they are hydronium ions (H3O+), not hydrogen ions.


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.
