Kind of. Very strong acids can be negative, just as very strong bases can go higher than 14. Its like this:
...-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19...
Water, which is neutral, is about a 7. Acids are less than 7 and bases are greater than 7, there is no limit on how strong (greater or lesser than 7) an acid or base can be, although an acid that is -1,000 on the pH scale, if it exists, will probably never be found.
Actually, yes. a pH can be below zero and above 14. To get a negative pH, the concentration of the hydronium ions produced by the dissolution of an acid must be greater than 1. For example, take 3M HCl (hydrochloric acid). It is considered a strong acid, and 3M HCl will dissociate into 3M Cl- and 3M H30+ (because strong acids are assumed to dissociate completely). Since the concentration of H30+ is 3, and the pH is equal to the negative log base 10 of the hydronium concentration, the pH here is equal to -0.48. Any concentration of hydronium ions in an acidic solution that is greater than 1 will result in a pH less than 0.
Technically it is possible to have a negative pH if you have a concentration of a strong acid higher than 1M (a 1M solution of a strong acid has a pH of 0), but most indicators and meters cannot measure such and acidic solution.
No, there are no negative values for pH; the only possible values range from zero to 14.
negative logarithm of hydrogen ion concentration
No they release Negative H ions when pH increases
pH is the negative log of the activity of the hydrogen ion in an aqueous solution. A powder is not a solution.
It can be below 1. It can also be negative.
HCl is a strong acid and dissociates completely. Therefore it can be found using the equation: ph= -log [H+]
Classify a substance that has negative pH value. Foods that have acids in them is a substance hat have pH.
The pH is the negative log of [H+].
Iron does not have a pH on its own. pH is the negative log concentration of H+. Iron can be affected by pH though.
hydrogen
pH is the negative logarithm of the hydrogen ion activity in a solution.
No, the pH is the negative logarithim to base 10 of the Hydrogen Ion concentration.
The pH of acids ranges between 1 to 6. The one with pH 1 is the most concentrated. The pH is a measure of the concentration of H+ ions in a solution.
There's no limit to acidity.
Yes and in fact it is possible to have a slightly negative pH. Battery acid is pH 0 or close. pH is the negative logarithim to base 10 of the Hydrogen ion concentration. So 1 molar HCl has a theoretical pH of - log10[1] = 0. So 2 molar H2SO4 is slightly negative if the math is done.
Yes, if the concentration of hydrogen ions is above 1 M, then pH will be negative. An example is Sulfuric acid, which can get a proton concentration up to 18 M which would be a pH of -1.3.
pH of a solution is the negative logarithm of the hydrogen-ion concentration
pH = - log [H3O+]. It is the negative logarithm of the hydronium ion concentration.
