The pH of a strong acid is typically close to zero, as strong acids completely dissociate in water to release H+ ions. The pH of a weak acid is usually higher than zero, as weak acids only partially dissociate in water, resulting in a lower concentration of H+ ions and a pH closer to 7.

Is it possible for a strong acid and a weak acid to have the same pH?
No, strong acids dissociate completely in water, resulting in a lower pH compared to weak acids which only partially dissociate. Therefore, a strong acid will always have a lower pH than a weak acid.
How does pH of a strong acid compare with the pH of a weak acid?
The pH of a strong acid is lower than the pH of a weak acid. This is because a strong acid completely dissociates in water, leading to a higher concentration of hydrogen ions and a lower pH. In contrast, a weak acid only partially dissociates, resulting in a lower concentration of hydrogen ions and a higher pH.
What is the pH difference between a strong acid and a weak acid n the pH scale?
Usually a strong acid will produce a lower pH, but not always. pH is not a measure of the strength of an acid (or base) but the acidity of a solution, which is dependent on both the strength of the acid or base and its concentration in the solution.
How can you differentiate strong acid from a weak acid using an indicator?
You can differentiate between a strong acid and a weak acid using an indicator by examining the pH change. A strong acid will cause a more significant decrease in pH and produce a more intense color change in the indicator compared to a weak acid, which will cause a less dramatic change in pH and produce a less intense color change.
Is pH 9 a strong or weak acid?
A pH of 9 is not acidic, it is basic. in order to be acidic the pH must be less than 7 It does not show whether the base is strong or weak as pH depends on both the strength of the acid/base as well as its concentration.

What should be pH -value to be strong acid?
The pH will depend on the concentration of the acid, not on whether it is strong or weak.

Would a strong acid have a lower pH level than a weak acid?
yes a strong acid would have a lower ph level
Which has a lower pH weak acids or strong acids?
strong acid
Is pH 9 a strong or weak acid?
A pH of 9 is not acidic, it is basic. in order to be acidic the pH must be less than 7 It does not show whether the base is strong or weak as pH depends on both the strength of the acid/base as well as its concentration.
If a substance has a pH of 6 is it a strong or werak acid?
Strong acids have pH values below 3 , so it is a weak acid.
When a buffer system forms a weak acid from a strong acid what happens to the PH?
The pH number will be higher
Is pH 2.1 a strong or weak acid?
It's considered a dilute acid, not a weak acid. That term has a very specific meaning. A strong acid is one that ionizes (many chemistry texts use the word "dissociate") completely in water, and a weak acid is one that doesn't completely ionize. Hydrochloric acid is a "strong" acid; hydrofluoric acid is a "weak" acid even though it's more corrosive than hydrochloric acid is. So...you could take hydrochloric acid (a strong acid) and mix it with a lot of water, get it up to pH 6, and still have a strong acid.
