Things to remember… • Label what the calculations are for • Watch sig figs • Include qualitative data • Improvements on lab itself-not how you did the lab • Watch GRAMMAR and spelling. • Overall-need more explanation of scientific concepts in analysis/conclusion.
Errors • How would those errors affect the results? • Comment on how the lab is set up, not “we may have measured wrong”, instead something like-”we should have measured the volume with a graduated cylinder rather than a beaker because it is more precise” • Why are those errors important/relevant?
Cu/Ag lab specifically • Ratios in balanced equation should match what you calculated. • If your calculations seem way off (ratio of 1:30), you need to have a reason why. • Major improvement/error was length of time it reacted. We assumed all the AgNO3 reacted, but we only let it go for 30 min. We should/could have easily tested to see if all AgNO3 was gone from solution.
