Striving for Accuracy

#1

We carefully measured the 5 mL of NaOH by bending down to eye level so we could accurately see the meniscus and add the needed amount of the NaOH during the first reaction.

#2

We carefully and slowly added the Cu3(PO4)2 through the filter to make sure all the solid remained in the filter, and all the liquid passed through, with no cave ins during the 6th reaction.

#3

During this reaction we had to repeated add H2SO4 through our previously produced solid so that all of the solid would drain into the bottom of the beaker and no copper would be left behind, during the 6th reaction.

#4

During the second reaction we had to carefully and accurately stir the solution while the color shift happened. If we did not do this correctly the solution would have started to pop and we would've gotten dangerous chemicals on us.
