for example:
0 sec
30 sec
60 sec
90 sec
or basically any time increment
for the experiment, i would wait x amount of time before filtering the solution for the precipitate.

if i were to use CuSO4(aq)  and Na2CO3(aq) and mix them with constant volume and other variables all throughout the experiment.
 would the mass of the precipitate differ for each time, and how so or would it stay constant?


any help is appreciateed


experimental data would vary but theoretically it should have some type of pattern..

  The mass of the precipitate should remain constant, given that the solutions had a good chance to mix.
