Strong vs Weak Acids

Postby Jessica Helfond 2F » Sat Jan 19, 2019 11:42 am

How do we know if an acid is strong or weak? Similarly, how do we know if a base is strong or weak?

You can determine the strength based on the Ka and Kb. If the Ka or Kb is smaller than 10^-3 then it is weak.

Yes, like Gavin said above, if the value of Ka or Kb is less than 10-3, then the acid/base is weak.
