It would be an acid since it is less then 7. Also, it is typically a weak acid since is it near a pH of 7 which is a neutral solution.
acid
That would be written as 0.2 mg.

'z' is used to denote integers in german. 'z' denotes zahlen
If I remember correctly, bases have low pH and acids have high pH; therefore, a base would definitely be less than 7.
A pH of 10 is a thousand times more basic (a base) than a pH of 7.
acid
A pH of seven is neutral.
pH 4 = acid pH 12= base
A pH that is less than 7 is an acid, so 4 pH would be an acid.
there is no logical reason to believe that "acetylsalicyclic acid" would have a pH of 15...this would be a base.
Acidic
-log(10^-4 M) = 4 14 - 4 = 10 pH
It is acutally pH. We use pH to see how many [H+] ions there are in a solution. Blood commonly has a pH of about 7.5-7.6 according to the person.
4 if its a base 1 if its an acid
3/4-6
The pH scale is from 1-14 Strong acids are 1-4
Lemonade is acidic and would have a pH in the 4.0 - 6.5 range.
