The pH scale does not have an easily defined lowest number. Often, answers of 1 or 0 are given, but not correct. The pH actually goes below zero, so that negative values are possible. In order to measure a pH there must be some water present, so the theoretical lowest pH value would be slightly less than -1.

What number range can you find an acid-in on the pH scale?
Acidic solutions have a pH under 7.
If an pH scale is up to 7 or 8 what does it mean?
If the number on the Ph scale is 7 then that means its neutral, neither an acid nor an alkali. If its eight, it is most likely an acid.
If something is a 0-6 on the pH scale what is it?
If something is a 0-6 on the pH scale it is an acid solution
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 substances have the lowest pH 0?
battery acid
Can the lowest acid on to pH scale kill you?
Definately
Which is a strong acid-pH 1 or pH 6?
The Lower The pH Scale The stronger the acid ph7 is neutral and the higher the scale past 7 the stronger the alkali is
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
On the pH scale what is the pH of an acid?
0 - 6.9 The lower the pH number the higher the concentration of hydronium ions and higher the strength of acid
What is an acid on the pH scale?
An acid is any substance below 7.0 on the pH scale. The lower the number, the stronger the acid. For instance, hydrochloric acid (HCl) in the stomach is typically at pH 1.0 - 2.5. The scale can range into negative numbers, but most substances are above pH 0.
What is acid measured on the pH scale?
An acid would be on the left side of a pH scale
What number range can you find an acid-in on the pH scale?
Acidic solutions have a pH under 7.
What does a low number on a pH scale say about a solution?
The solution is an acid.
What colour is acid on a PH scale?
The Ph scale does not have colours.
If an pH scale is up to 7 or 8 what does it mean?
If the number on the Ph scale is 7 then that means its neutral, neither an acid nor an alkali. If its eight, it is most likely an acid.
What number on the pH scale indicates the strongest acid solution?
The pH scale does not indicate the strength of the acid, so there is no number on the pH scale that indicates the strongest acid. A pH value of zero will be the most concentrated strong acid, but even that isn't exactly correct. Concentrations greater than 1 M have pH values <0, but are not useful values because of intermolecular interactions and activity values.
What is the pH scale of the strongest Alkali?
The strength of an acid and alkali is shown using the pH scale which goes from 0 to 14 . pH number of acid is less than 7. and pH number of alkali is greater than 7. that's why the smaller the number the stronger the acid and the larger the number the stronger the alkali. so pH of weak acid is 6 and pH of strong alkali is 14 because if the smaller number shows the stronger acid, the larger number shows the weaker acid. And as larger number shows strong alkali, the pH scale is from 0 to 14; so 14 shows stronger alkali.
