No, because of the way pH is defined. It is the negative log of the Hydrogen ion concentration. In water the extreme values of hydrogen ions are 0 and 14 corresponding with 1 and 1*10-14. Any higher hydrogen ions than this and the solution would become electrostatically positive.

If we assume that ph is a matter of hydrogen ion concentrations in water (as it 'always' is) then we cannot have a negative ph value. It comes down to the electro-static behavior of water.
But if we are willing to state that ph is simply a matter of hydrogen atom concentrations then, yes, we could have negative ph values.
For example if we were to have one liter of hydrogen gas at STP then we would have 44 moles of hydrogen gas per liter. Which would give 88 moles of hydrogen atoms per liter, making a concentration of 88M.
The negative log of 88 is -1.95.
But discussion ph outside of a aquatic situation is kind of silly.

∙ 10y agoYes. The pH scale is open-ended. The strongest acid is fluoroantimonic acid, formula H2FSbF6. This stuff can easily produce pH -16.
Problem is, pH meters are not usually designed to measure these values, and buffers for calibrating meters don't go that low.

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.
