None. In a solution with a pH of 7 the hydrogen ion concentration is equal to the hydroxide ion concentration.
Best example : water! H2O...it is H1OH1
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.
A solution with a greater concentration of hydrogen ion (H+) than hydroxide ion (OH-) is an acid while the inverse would be a base.
A common concentration of ammonium hydroxide solution is 25 %.
None. In a solution with a pH of 7 the hydrogen ion concentration is equal to the hydroxide ion concentration.

No, the pH is the negative logarithim to base 10 of the Hydrogen Ion concentration.
How to work it out - Calculate the concentration of the solution in terms of molarity. Calculate the hydrogen ion concentration from the fact that multiplying the hydrogen and hydroxide concentrations (in mols per litre) will always give 1x10-14. Take the -log10 of the hydrogen ion concentration.
A common concentration of ammonium hydroxide solution is 25 %.
At pH 7, the concentration of hydroxide and hydrogen (hydronium) ions is equal; both concentrations are equal to 10-7 mol/L.
A base or alkaline substance lowers the H (hydrogen ion) concentration in a solution. Bases can accept or remove hydrogen ions from the solution, increasing the concentration of OH- ions and thereby reducing the concentration of H+ ions. Examples of bases include sodium hydroxide (NaOH) and ammonia (NH3).
It produces a neutral salt along with water
