It depends on how concentrated the acid is. Say it's .00001 M HClO4. pH = -log([H+]). In this case, [H+] = .00001 M, and thus -log(.00001) = 5.

Which is the most acidic pH 2 pH 5 pH 7 or pH 11?
Most acidic is substance of pH of 2, then of pH of 5 and the substance of pH 7 is neutral and the substance of pH 11 is basic
If the ph of a substance is 11 then that substance is?
If a substance has a PH of 11 then the substance is basic.
What substance has a pH level of 5?
there are a lot of things that have a pH OF 5 some aee pure rain water and black coffee.
What is alkalis acid?
Alkali isn't an acid. Alkali and acid are terms used when the pH of a substance is a certain number, for example if a substance has a pH of 1, 2, 3, 4, or 5, then the substance is an acid. If the pH is 11, 12, 13, 14 or 15, then the substance is an alkali.
What is the pH of a substance?
The pH is the negative log of the concentration of hydronium ions. (pH=-log [H3O+]) If the pH is high, the substance is basic. If it is low the substance is acidic. When the pH is exactly 7 the substance is neutral.
Which is the most acidic pH 2 pH 5 pH 7 or pH 11?
Most acidic is substance of pH of 2, then of pH of 5 and the substance of pH 7 is neutral and the substance of pH 11 is basic
Is 5 on the pH scale acidic or alkaline?
If a substance has a pH of 5, it is said to be weakly acidic.
What is a substance which is pH 6?
Natural rainwater (pH 5 - 6) Milk (pH 6 - 6.6)
Which has the greater concentration of hydrogen ions a substance with a pH of 5 or a substance with a pH of 4?
A pH of 4 is one order of magnitude more acidic that a pH of 5. So. the 4 pH has the greater hydrogen ion concentration.
If the ph of a substance is 11 then that substance is?
If a substance has a PH of 11 then the substance is basic.
What substance has a pH level of 5?
there are a lot of things that have a pH OF 5 some aee pure rain water and black coffee.

Is a solution of pH 5 acidic?
It's not very acidic, but yes it is. Any pH lower than seven is considered to be acidic, and any pH higher than seven is basic. If a substance has a pH of 7, that means the substance is considered to be neutral.
A solution with pH value of 6 or 5 which will be more acidic and why?
The substances with pH 5 is more acidic since it contains more H+ ions. As the pH goes down the substance becomes more acidic and as it goes up the substance becomes more basic.
If a substance has a pH of 5 where would it be on the acidity scale?
Somewhat acidic since 7 is the neutral point on the pH scale.
A substance has a pH of 7. Which of the following descriptions matches this pH?
A substance with a pH of 7 is not acidic nor is it basic. It is a neutral substance.
