The answer to this question is 14 (I believe!). This is the PH Scale: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 All these All these numbers from numbers from 7 - 14 are alkalis. 1 - 7 are acids. The middle of the PH Scale is 7; what we call Neutral (this is because it is neither Acid or Alkalis). I hope this answer helps you.

It is often taught , sometimes even in A level chemistry classes, that 14 is the maximum possible value of pH and the minimum value is 0.
This is definitely wrong.
Although most solutions are in the range 0 - 14, concentrated solution can be outside this range.
A concentrated solution of sodium hydroxide would have a pH of about 15.
A concentrated solution of hydrofluoric or hydrochloric acid would be have a pH of about -1.

What is the highest pH level for a base?
pH can exceed 0 and 14 infinitely. Which means it can be any number from negative infinity to positive infinity (tho it does not exist in real life). So there is no so called highest/lowest pH level.
What is the highest pH level of acid?
The highest pH level of acids is upto 14.
At what pH did you see the highest activity of salivary amylase?
pH of about 7
How do indicators distinguish acids and bases?
By the pH, or more specific, the amount of positive hydrogen atoms. The higher the number pH, the lower the acidity (i.e. 14 pH is the most basic base, 1 being the highest).
Weakest pH of acid?
The highest pH an acid can have is just below 7.
What number is highest on the pH scale?
The highest number on the pH scale is 14. The pH scale goes from 0 to 14.
What are the highest number and lowest number on the pH scale?
1 is the lowest 14 is the highest and 7 is the middle
Is the base the highest number on a pH scale?
Yes. A base has a pH of greater than 7. An acid has a pH of less than 7.

What substance has the highest ph?
an alkali
The highest pH of a fruit?
Banana
What is the highest pH level humans can handle?
9.5 is the highest recommended.
Weakest pH of acid?
The highest pH an acid can have is just below 7.
Where is the pH in the digestive system the highest?
The stomach has an average pH of 2 or 3 this is the highest. Used to break down proteins.
