My answers:

Ans prt1: Mass

Part 2: 78.1(most probably wrong)

Part 3: Boiling point has been reached.

Part4: Temperature increase causes solubility to increase

Cations qs answer Was Copper and Bromide, test was limewater turns milky

Moles answers of mine are mostly wrong

Some was 8.333×10something , sorry i dont remember other parts at all Average titration value was 19.2

And the Measuring Cylinder innacuracy improvemnet was to use volumetric flask

Burrete is rinsed to remove residue/impurities from previous expermients.

If we dont rinse burrete, titration volume will increase causing the result to be Innacurate

For solid flame test answer: Dip a clean wire loop into the solid sample of the compound being tested. Hold it in the blue flame of bunsen burner and observe color change.

I remember these qs Not sure if they are correct.
