Silver Chromate Lab Report
Theoretical Ksp value of silver chromate taken from table 17.1 on p. 5, Lesson 17.
% error = (experimental – theoretical) x 100 theoretical = (1.6 x 10-11 – 1.1 x 10-12) x 100 1.1 x 10-12 = 1354.545455
Therefore, the percentage error is 1400% (rounded to significant figures) and this is a large percentage error.
c. There are a couple of sources of error that could have contributed to this large percentage error. One could have been that the beaker was left in a spot where the temperature was not 25 °C. The Ksp values found in table 17.1 were measured at 25°C (standard conditions) which means if the experiment was done at a different temperature
