accuracy of the pH paper. my school used pH indicator paper, and it only gave us rough estimates of the pH based on the color the strip would turn. so instead of 4.36, we got 4. this caused a lot of percent error and it also caused the pKa to be less accurate, which means the Ka was less accurate.

∙ 9y agoSince pKa values are estimations, they can have sources of error. Some possible sources include incorrect measurements of non-aqueous solvents, which is needed for the estimation, or an error in calculating the equation..
