Questions Could this experiment have been done in a different order? For example, Fe filings being removed at the end of the scheme. Why or why not? 1. Sublimation is a common technique used in separation schemes. Naphthalene, found in mothballs, sublime easily. How can naphthalene be separated from a mixture of KBr and sand. 2. way naphojene 3. Consult a handbook to answer the following questions: a. Separate NiCO, from Na,CO, 70 b. Separate AgCl from NaC Separate TeO, from Sio, c. L I Scparation of the Componeats of a Misture 31

Explanation / Answer

Q: 1 NiCO3 is insoluble in water while Na2CO3 is soluble in water.so dissolve the mixture in water whereby Na2CO3 dissolve leaving behind Ni2CO3.

Q:2 Agcl is insoluble in water while Nacl is soluble therefore dissolve the mixture in water whereby Nacl dissolve leaving pure Agcl in solid phase.

Q:3 Add the mixture containing SiO2 and TiO2 in HF where SiO2 dissolve leaving behind Pure TiO2

From above three solution we can again get the dissolved components by crystallization
