Is it possible to have 0 pH?

Answer 1

Yes, because pH is based on the concentration of H+. Try calculating the pH of a concentrated acis, it will have a negative pH.

Answer 2

Most substances have a pH in the range 0 to 14, although extremely acidic or extremely basic substances may have pH less than 0 or greater than 14. An example is acid mine runoff, with a pH = –3.6. Note that this does not translate to a molar concentration of 3981 M; such high activity values are the result of the extremely high value of the activity coefficient while concentrations are within a "reasonable" range [9]. E.g. a 7.622 molal H2SO4 solution has a pH = -3.13, hydrogen activity αH+ around 1350 and activity coefficient γH+ = 165.4 when using the MacInnes convention for scaling Pitzer single ion activity coefficient

Answer 3

maximum components have a pH in the type 0 to 14, even nonetheless fairly acidic or fairly mandatory components would have pH below 0 or larger than 14. An occasion is acid mine runoff, with a pH = –3.6. be conscious that this does not translate to a molar understanding of 345c48cce2e2d7fbdea1afc51c7c6ad2681 M; such top game values are the effect of the fairly top importance of the game coefficient collectively as concentrations are interior a "straightforward" sort [9]. E.g. a 7.622 molal H2SO4 selection has a pH = -3.13, hydrogen game ?H+ around 1350 and game coefficient ?H+ = one hundred sixty 5.4 collectively as applying the MacInnes convention for scaling Pitzer single ion game coefficient

Answer 4

pH is a measure of the acidity or alkalinity of a solution. Solutions with a pH less than seven are considered acidic, while those with a pH greater than seven are considered basic (alkaline). pH 7 is considered neutral because it is the accepted pH of pure water at 25 °C, although, strictly, pure water cannot be assigned a pH value. pH is formally dependent upon the activity of hydrogen[1] ions (H+),[2] but for very pure dilute solutions, the molarity may be used as a substitute with some sacrifice of accuracy.[3] Because pH is dependent on activity, a property which cannot be measured easily or predicted theoretically, it is difficult to determine an accurate value for the pH of a solution. The pH reading of a solution is usually obtained by comparing unknown solutions to those of known pH, and there are several ways of doing this.

The concept of pH was first introduced by Danish chemist S. P. L. Sørensen at the Carlsberg Laboratory[4] in 1909. The name, pH, has been purported to come from a variety of places including: pondus hydrogenii (Latin),[5] potentiel hydrogène (French), and potential of hydrogen (English).[6] However pH is actually a shorthand for its mathematical approximation: in chemistry a small p is used in place of writing − log10 and the H should more correctly be [H+], standing for concentration of hydrogen ions.

Answer 5

Sure. pH is defined as the -log[H+], meaning the concentratio of H+ ions is 10^(-7) molar. Therefore, a pH of 0 would be 10^(0) = 1 molar. So if you made a 1 molar (or 1 normal) solution of HCl, hydrochloric acid, you would have a pH of 0.

You could even have a pH of -1 if you could make a 5 molar solution of sulfuric acid (H2SO4)

Answer 6

but guys at such high [H+] it would be unclear which is the solvent and which is the solute. you could say that water is dissolved in pure acid. for pH=0 it would be almost a drop of water in a beaker of pure h2so4. when the acid is no longer the solute in the system, the term pH is meaningless. that is why you dont say ph=0, though it exist. molten strong acid

Answer 7

theoretically possibe. pH is measured as the negative logarithm (with base 10) of the concentration of hydrogen ions in the solution. having a 0 pH means conc. of H ions must be 1 mol/dm3 which is a very very high number and is practically not possibe.

Answer 8

Yes. I've long known that 1M
(Molar) HCl has a pH of 0

Answer 9

y not what is log 1.its zero
so 1M (36.5 grams in 1 litre sol.)HCl will give 1 M of H+ ions so
pH= -log (1)= -0= 0
it's practically very difficult

Answer 10

yes. whe concentration of H+ ions is 1 M
