Does a pH value signify certain number of hydrogen or hydroxide ions?

"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-

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.
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.
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
Determine the number of moles of sodium hydroxide produced when 2 moles of sodium and 3 mol of water react to form soduim hydroxide and hydrogen gas?
Na +H2O -> NaOH +(1/2)H2 Every mole of Sodium requires one mole of water to make one mole of Sodium Hydroxide. So two moles of Sodium will produce two moles of Sodium Hydroxide. If there are three moles of water in the initial reaction then there will be one mole of water left over after reacting with two moles of Sodium. This reaction will produce half a mole of hydrogen gas.
What group number is hydrogen?
The element Hydrogen is in the group number 1.
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 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.
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.
Why is water considered to be a neutral?
Because the number of hydrogen ions are the same as the number of Hydroxide ions.
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.
What is pH pure water (neutral)?
pure water is neutral with a pH of 7
What is the number of atoms in cupric hydroxide?
5 atoms = 1 Copper + 2 Hydrogen + 2 Oxygen
What Is a substance that produces hydroxide ions in solution.?
A base does this. The hydroxide (OH-) ion appears in solution. An acid produces hydrogen (or hydronium) ions in solution, and not hydroxide ions.
What is the oxidation number of ferrous hydroxide?
+2 for iron, +1 for hydrogen and -2 for oxygen in Fe(OH)2
In a titration when the number of moles of hydrogen ions equals the number of moles of hydroxide ions what is said to have happened?
the equivalence point has been reached
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.
