HOW CAN YOU COMPARE THE STRENGTHS OF WEAK ACIDS?

 

 

 

It is stronger if: 

1.   Ka value is larger   

2.   pKa value is smaller

3.  The equilibrium is shifted farther to the right.    

4.  The ionized form of the acid exceeds the molecular form

5.  pH is smaller

6.  The % dissociation is larger.
