Who committed the crime? (1 T/I)
None of the restaurant staff had pleaded to using Sodium bicarbonate, ergo none of the staff could have been guilty of leaving Mr.Price in a critical condition.
Explain how you used the properties from your observation table to make conclusions about the identification of the substances. Use specific information from your lab to support your conclusions. (4 T/I)
Firstly, it can be see in the chart that Sodium bicarbonate and the unknown substance ha every similar and almost the same physical properties …show more content…
I had also identified the correlation between Sodium bicarbonate and the unknown substance in terms of how they both react with water (neither of them dissolve in the water, rather is more dense than the water which seemingly causes the Sodium bicarbonate or Unknown substance to sink to the bottom of the platform. The Sodium bicarbonate and Unknown substance had reacted alike when they make contact with acidic acid. Being that they become extremely reactive with the acidic acid, forming consecutively larger bubbles until the solute (being Sodium bicarbonate) had completely dissolved in the acidic acid. Using the universal indicator it can be observed that the Unknown substance or Sodium bicarbonate had both became a chunky paste, which turns into a dark green colour which signifies that it is a moderately neutral-weak acid. Finally, when comparing the Unknown substance and the other substances that had been listed, I had found that Sodium bicarbonate had proudly fitted the results like those of the Unknown substance’s, those results being, they had both dissolved quite well into the iodine solution and later became a viscose, dense, and rather lavish orange colour. I can conclude that from my very
