## Is pH above 14 possible?

Thus, measured pH values will lie mostly in the range 0 to 14, though negative pH values and values above 14 are entirely possible.

Since pH is a logarithmic scale, a difference of one pH unit is equivalent to a tenfold difference in hydrogen ion concentration..

## Is a pH of 10 basic?

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. … For example, pH 10 is ten times more alkaline than pH 9 and 100 times (10 times 10) more alkaline than pH 8.

## Is the pH scale logarithmic?

The pH scale is logarithmic, essentially meaning the difference in 1 pH unit is a difference of 10 times! Last week we introduced exactly what we are measuring when we take a pH measurement – hydrogen ion activity.

## Is a pH of 15 possible?

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.

## Which is strongest acid in the world?

carborane acidThe world’s strongest acid, at least a million times more potent than concentrated sulphuric acid, has been made in a lab in California. Perhaps confusingly, it is also one of the least corrosive. The compound, called a carborane acid, is the first ‘superacid’ that can be stored in a bottle, say its creators.

## Why can pH be negative?

It’s possible. If the molarity of hydrogen ions is greater than 1, you’ll have a negative value of pH. For example, you might expect a 12 M HCl solution to have a pH of -log(12) = -1.08.
