Identifying the Weakest Acid

Explanation of Acid Strength

Acid strength is determined by the ability of an acid to donate a proton (H+ ion) in a solution. The strength of an acid is measured by its dissociation constant (Ka). The higher the value of Ka, the stronger the acid is.

Determining the Weakest Acid

Among the given acids, the one with the lowest Ka value is the weakest acid.

Phenol (Ka=1.3x10*-10)

HCN (Ka=4.9x10*-10)

CH3COOH (Ka=1.8x10*-10)

Benzoic acid (Ka=6.5x10*-5)

Comparing the Ka values, it can be observed that phenol has the lowest Ka value among the given acids, making it the weakest acid.

Conclusion

Phenol is the weakest acid among the given options based on its low Ka value. It has a weak ability to donate protons in a solution compared to the other acids.
