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.
A pH of 4 would denote a solution that is acidic. pH values below 7 indicate acidity, with lower values representing stronger acidity.
pH 4 = acid pH 12= base
-log(10^-4 M) = 4 14 - 4 = 10 pH
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.
4 if its a base 1 if its an acid
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.
A pH of 7 denotes a neutral solution, meaning it is neither acidic nor alkaline. Water typically has a pH of 7, which indicates a balanced concentration of hydrogen ions and hydroxide ions.
3/4-6
The final pH would be less than 5 because the stronger acid (pH 4.0) would have a greater effect on the overall pH than the weaker acid (pH 6.0). To calculate the exact final pH, you would need to know the exact concentrations of the two solutions and perform a Henderson-Hasselbalch calculation.
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.
