The percentage error in the experimental determination is 124%.
The experimentally determined value for Ksp = 1.5×10^−10
The accepted value of Ksp = 1.2 × 10^−12
The formula for percentage error is;
% error = absolute value of ( actual value - experimental value)/actual value × 100/1
% error = absolute value of (1.2 × 10^−12 - 1.5×10^−10)/ 1.2 × 10^−12 × 100/1
% error = 124%
