A group of students investigated the effect of temperature of vinegar on its reaction time with baking soda. To minimize the random errors, they did 3 trials for each temperature change. The following data were collected. At 30 °C, the times it takes for baking soda to react in seconds are 30.1, 30.9 and 30.2 for Trials 1, 2 and 3 respectively. At 55 °C, they recorded the reaction times for the three trials as 25.6 s, 25.9 s and 25.5 s. At 60 °C, the data were 20.0 s, 19.8 s and 19.3s for the three trials. At 75 °C, they recorded the reaction times for the three trials as 15.0 s, 15.2 s and 15.5s. At 90 °C, the reaction times gathered for the three trials are 8.3 s, 8.9 s and 8.8 s.

Using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 pb+2(aq) + 2cl -(aq). if the value of ksp was determined to be only 1.2 x 10-2: too much solid has dissolved. additional precipitate is forming. the solution is unsaturated. the ions are now combining to reduce their concentrations.
