| Increasing pH (Decreasing Acidity) Substances | 0 (most acidic) Hydrochloric acid (HCl) | 1 Stomach acid | 2 Lemon juice | 3 Cola, beer, vinegar |

Can something have a pH of 1?
But the scale does not have fixed limits, so it is indeed possible to have a
pH above 14 or below zero
. For example, concentrated hydrochloric acid can have a pH of around -1, while sodium hydroxide solution can have a pH as high as 15.
What products have a pH of 1?
| 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 |

What type of pH is 1?
Anything below 7.0 (ranging from 0.0 to 6.9) is acidic, and anything above 7.0 (from 7.1 to 14.0) is
alkaline
. The blood in your veins is slightly alkaline (pH = 7.4). The environment in your stomach is highly acidic (pH = 1 to 2).
What does a pH of 1 mean?
pH is a measure of how
acidic/basic water
is. The range goes from 0 – 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.
What has a pH level of 0?
| pH Value H + Concentration Relative to Pure Water Example | 0 10 000 000 battery acid | 1 1 000 000 gastric acid | 2 100 000 lemon juice, vinegar | 3 10 000 orange juice, soda |

Is bleach an acid or base?
Chlorine bleach is
a base
and is especially good at removing stains and dyes from clothes as well as disinfecting.
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.
Why pH is not less than zero?
The pH range does
not have an upper nor lower bound
, since as defined above, the pH is an indication of concentration of H+. For example, at a pH of zero the hydronium ion concentration is one molar, while at pH 14 the hydroxide ion concentration is one molar. … Yes, pH can be less than zero and more than 14.
How is pH calculated?
To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression:
pH = – log [H

What would be the pH of an acid?
A pH of 7 is neutral.
A pH less than 7 is acidic
. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value.
Is vinegar an acid?
Vinegar is acidic
. Vinegar's pH level varies based upon the type of vinegar it is. White distilled vinegar, the kind best suited for household cleaning, typically has a pH of around 2.5. Vinegar, which means “sour wine” in French, can be made from anything containing sugar, such as fruit.
Who discovered pH?
Søren Sørensen
. In 1909 Sørensen, a Danish chemist, introduced the concept of pH as a convenient way of expressing acidity.
Is blood acidic or basic?
The acidity or alkalinity of any solution, including blood, is indicated on the pH scale. The pH scale, ranges from 0 (strongly acidic) to 14 (strongly basic or alkaline). A pH of 7.0, in the middle of this scale, is neutral. Blood is
normally slightly basic
, with a normal pH range of about 7.35 to 7.45.
What is pH short for?
The H in pH stands for hydrogen. But, there is some controversy as to what the p represents. The Carlsberg Foundation itself says pH means “
power of hydrogen
“.
