Can you have a pH above 14?
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 food has the highest pH?
Here’s a list of vegetables and their pH levels:sauerkraut (pH: 3.30–3.60)cabbage (pH: 5.20–6.80)beets (pH: 5.30–6.60)corn (pH: 5.90–7.50)mushrooms (pH: 6.00–6.70)broccoli (pH: 6.30-6.85)collard greens (pH: 6.50–7.50)
Why does pH and pOH equal 14?
Correct answer: pH and pOH are the log concentrations of protons and hydroxide ions, respectively. The sum of pH and pOH is always 14. This is because the product of proton concentration and hydroxide concentration must always equal the equilibrium constant for the ionization of water, which is equal to .
What fruit has the highest pH?

Does lemon make water alkaline?
Lemon juice in its natural state is acidic with a pH of about 2, but once metabolized it actually becomes alkaline with a pH well above 7. So, outside the body, anyone can see that lemon juice is very acidic. However, once fully digested, its effect is proven to be alkalizing with many health benefits.
What is the highest pH level possible?
The highest possible pH is then 16.5, from the relation pH = 14 – pOH (under normal conditions) where we instead assume that all water molecules have been deprotonated (pOH = -2.5).
What is the lowest pH possible?
Since pH is defined as minus the logarithm of a number whose value is between 0 and 1, theoretically, the lowest value of pH is zero (0), which means a hydrogen ion activity of 1, which means basically that hydrogen ions (i.e. protons) are all that is present.

What is the pH of pure water?
7The pH of pure water is 7, the negative logarithm of 1 X 10-7. A neutral solution is one that is neither acidic nor basic. The hydrogen ion concentration equals the hydroxide ion concentration, and both equal 1 X 10-7 M.

Can you have a pH less than 1?
It’s definitely possible to calculate a negative pH value. … In practice, any acid that yields a concentration of hydrogen ions with a molarity greater than 1 will be calculated to have a negative pH. For example, the pH of 12M HCl (hydrochloric acid) is calculated to be -log(12) = -1.08.
Is a pH of 14 dangerous?
In terms of pH hydrofluoric acid is considered a weak acid – it does not fully ionize in water – but it is extremely dangerous because of how corrosive it is. … Liquid Drain Cleaner: pH = 14.
What is the pH of a banana?

Why pH is not more than 14?
pH = 14 corresponds to an aqueous solution of a strong base of molarity 1. By the same definition, pH = 0 corresponds to an aqueous solution of a strong acid or molarity 1. Higher concentrations result in pH > 14 for strong bases and pH < 0 for strong acids. ... So, that's why, the pH is not more than 14.
What pH is a lemon?
Lemon juice in its natural state is acidic with a pH of about 2, but once metabolized it actually becomes alkaline with a pH well above 7.
