The pKa of acetic acid in water is 4.76. What effect will a decrease in the polarity of the solvent have on the pKa? Why?

Short Answer

Expert verified

The pKa would increase (it would be a better acid) because of a decreased tendency to form a charge species in a less polar solvent.

Step by step solution

01

Explanation

When acidic acid dissolves in water It acts as a bronsted- lowry acid by donating a proton to the water in the reaction then the acidic acid is left as an anion.

When we decrease the polarity of the solvent then acetic acid tendency to form a charge species will become less. Hence pKa value of the acetic acid will increase.

02

Final answer

The pKa would increase (it would be a better acid) because of a decreased tendency to form a charge species in a less polar solvent.
