| pH Value H + Concentration Relative to Pure Water Example | 1 1 000 000 gastric acid | 2 100 000 lemon juice, vinegar | 3 10 000 orange juice, soda | 4 1 000 tomato juice, acid rain |

Can you have a pH of 1?
The pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic. … However, the environment inside your
stomach is highly acidic
, with a pH of 1 to 2.
What has a pH of 1?
| Increasing pH (Decreasing Acidity) Substances | 0 (most acidic) Hydrochloric acid (HCl) | 1 Stomach acid | 2 Lemon juice | 3 Cola, beer, vinegar |
|---|
What is the concentration of pH 1?
| Molar Concentration of HCl pH defined as Concentration Experimentally Determined pH | 0.0100 2 2.04 | 0.100 1 1.10 | 0.40 0.39 0.52 | 7.6 -0.88 -1.85 |

Is a 0 pH possible?
When a base, or alkali, is dissolved in water, the pH will be greater than 7. A solution of a strong acid, such as hydrochloric acid,
at concentration 1 mol dm
− 3
has a pH
of 0. … Thus, measured pH values will lie mostly in the range 0 to 14, though negative pH values and values above 14 are entirely possible.
Why pH is from 1 to 14?
One far end is not more than 1M of hydrogen ions, which results in a pH value of not more than 0. While on the other end is
not more than 1M of hydroxide ions
which results in a pH value of not more than 14. … The pH value goes out of the 0-14 range when the concentration of the solution exceeds 1M.
What number is most acidic?
The scale has values ranging from
zero
(the most acidic) to 14 (the most basic). As you can see from the pH scale above, pure water has a pH value of 7. This value is considered neutral—neither acidic or basic.
Can you have a pH less than 1?
A 1N solution of a strong acid gives a pH of 0. If your acid solution is stronger than 1N, then you will get a pH
less than 0
(a negative pH). It’s possible. If the molarity of hydrogen ions is greater than 1, you’ll have a negative value of pH.
What does a pH of 14 mean?
pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. … As this diagram shows, pH ranges from 0 to 14, with 7 being
neutral
. pHs less than 7 are acidic while pHs greater than 7 are alkaline (basic).
What does a pH of 0 mean?
A solution that has a pH of 0 is
very acidic with a high concentration of hydrogen ions
(although things can be of greater acidity), a pH of 7 is a neutral solution, equal concentrations of hydrogen ions and their basic counterpart hydroxy ions. … The H in pH stands for hydrogen.
Is pH above 14 possible?
The pH scale describes how many hydrogen ions (protons) are present in a solution. The pH scale typically stretches from zero to 14, passing through a neutral pH7 (freshly distilled water). … But the scale does not have fixed limits, so
it is indeed possible to have a pH above 14 or below zero
.
What is pH of 0.01 m NaOH?
This will produce a pH of
13
. Therefore, the pH of 0.1 M NaOH solution is 13. Note: The pH scale, which ranges from 0 to 14, tells you how acidic or alkaline a solution is. A pH lower than 7 is acidic, while a pH higher than 7 is alkaline.
Is a pH of 10 acidic or basic?
| pH Value H + Concentration Relative to Pure Water Example | 6 10 urine, milk | 7 1 pure water |
|---|
Why is a pH of 0 or 15 Impossible?
A saturated sodium hydroxide solution (NaOH) solution is supposed to have a pH of 15 based on its molarity. However, the
chemical will not be able to solvate entirely due to the presence of water
, which acts as a hindrance to the solvation (breakdown) of larger molecules.
What is the lowest pH ever recorded?
The lowest value recorded was pH
2.85
, and the highest was 5.95 pH. Between 1969 and 1974, no pH reading exceeded 5.0.
What is the world’s strongest super acid?
Fluoroantimonic acid
is the strongest superacid based on the measured value of its Hammett acidity function (H
0
), which has been determined for different ratios of HF:SbF
5
.
