Best example : water!
H2O...it is H1OH1
None. In a solution with a pH of 7 the hydrogen ion concentration is equal to the hydroxide ion concentration.
It is a basic solution, pH above 7
acidic
Water (H2O)
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.
None. In a solution with a pH of 7 the hydrogen ion concentration is equal to the hydroxide ion concentration.
< 7
Acidic
It is a basic solution, pH above 7
acidic
Water (H2O)
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.
Basic solutions are solutions that have more than a 1E-7 concentration of hydroxide ion. Thus, solutions with "extra" hydroxide ions are basic. On the other hand, solutions with extra hydrogen (hydronium) ions are acidic.
A solution with a greater concentration of hydrogen ion (H+) than hydroxide ion (OH-) is an acid while the inverse would be a base.
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 %.
