Answer:
Explanation:
The objective of this experiment is to match the expected result with each of the propositions given after the experiment had been carried out.
1. The top layer was the <u>organic </u> layer. This is because all the organic compounds have lesser density than water except chloroform that will be formed when NaOH is added.
2. 9-fluorenone was most soluble in the <u>organic </u>layer. This is so as a result of its non-polar carbon structure.
3. Deprotonated chloroanilic acid was most soluble in the <u>aqueous </u>layer as a result of the formation of an electrovalent bond with water.
4. The bottom layer was the <u>aqueous </u>layer as a result of the huge amount of water density.
5. The organic layer was a <u>yellow</u> colored solution.
6. The aqueous layer turned into a <u>pink</u><u> </u> colored solution.
Answer:
NaOH is limiting
Explanation:
Hcl + NaOH ------------ Nacl + H2O
Given 7.81g 5.24g
mol weights 1+35.5 23+16+1
36.5 40
No of Moles 7.81/36.5 5.24/40
0.2139 0.131
No of moles = weight/ molecular weight
No of moles of NaOH is lower so it is limiting as according to equation one mole of Hcl requires mole of NaOH so equal number of moles are required. NaOH is 0.131 which is far lower than 0.2139
