Problem: Given the following acids and Ka values:HCN =  4.93 x 10-10HF = 3.53 x 10-4HOAc =  1.76 x 10-5Which acid is the strongest?A. HOAcB. HCNC. HFD. All are equally strong

FREE Expert Solution

Ka represents the acid dissociation constant and it measures the strength of weak acids. 

In general:

• The higher the Ka the stronger the acid and the greater the concentration of H+
• The lower the Ka, the weaker the acid and the lesser the concentration of H+
