The concentration of hydrogen ion in a sample of soft drink is 3.8xx10^(-3)M. What is its pH ? |
|
Answer» Solution :Here, we are given that `[H^(+)]=3.8xx10^(-3)M` `PH=-log [H^(+)]=-log (3.8xx10^(-3))=-(log 3.8 + log 10^(-3))=-0.58 + 3 = 2.42 = 2.42` As pH is LESS than 7, the SOFT drink is acidic. |
