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.

∙ 10y agoActually, 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.

What the PH?
negative logarithm of hydrogen ion concentration
What is the pH value of bread?
pH is the negative log of the activity of the hydrogen ion in an aqueous solution. A powder is not a solution.
Do buffers release H plus ions when pH increases?
No they release Negative H ions when pH increases
Why pH can not be below 1?
It can be below 1. It can also be negative.
How calculate pH for a solution?
HCl is a strong acid and dissociates completely. Therefore it can be found using the equation: ph= -log [H+]
How will you classify a substance having pH value negative?
Classify a substance that has negative pH value. Foods that have acids in them is a substance hat have pH.
How does one calculate the pH of the solution?
The pH is the negative log of [H+].
What is the pH of iron?
Iron does not have a pH on its own. pH is the negative log concentration of H+. Iron can be affected by pH though.
PH is the negative logarithm of the?
hydrogen
What are characteristics of pH?
pH is the negative logarithm of the hydrogen ion activity in a solution.
Is the pH of solution is the negative logarithm of its hydroxide ion concentration?
No, the pH is the negative logarithim to base 10 of the Hydrogen Ion concentration.
What is the pH of acid?
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.
Can pH be negative?
There's no limit to acidity.
Are there any acids with a pH of 0?
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.
Can pH be a negative number?
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.
Why is there a minus sign on the definition of pH?
pH of a solution is the negative logarithm of the hydrogen-ion concentration
What is the formula of calculating pH?
pH = - log [H3O+]. It is the negative logarithm of the hydronium ion concentration.
