Exercise 2

Data Table 2 Summary of Separation

Questions

1. The % of mixture of solids (initial) recovered

Initial mass 6.3 g

Samples total mass = 1.2 + 0.9 + 1.8 +1.3 = 5.2g

The percentage error = ((5.2-6.3)/5.2) x 100 = 21.15%

1. Possible error sources to explain for the deviation between (% of the total mass of the mixture of solids (initial) and the total sum of components separated)

• An error during calculation may be a factor
• The salt and water evaporated too much after boiling for long
• Some materials may have been lost or left behind during the transferring process

1. The challenging part of them during the experiment was keeping the cat off the table 1, where I was working from as it was disturbing my materials and substances. Apart from that, I found the experiment more enjoyable and never found any steps which were challenging.

Conclusions

Through the learning of the simple methods of mixture separation as well as their components was interesting to observe mostly on how various properties were interacting. The changing of mass and how the mass was affected. Also, I felt that mixture separation generated a better understanding of mixtures. Moreover, the separation process of the experiment that involved iron fillings and sand while the magnet was reminded me of another magnetic childhood toy together with a magnetic wand. We would drag the shavings of the iron designing a board face. Lastly, it was very interesting to see the chemistry that designs numerous materials that are enjoyed in each and every day of our life.
