What are soluble impurities. (b) Do soluble impurities in solids effect the melting point of the sample? if so, what are the effects?(c) What are insoluble impurities? (d) Do insoluble impurities in solids effect the melting point of the sample? if so , what are the effects?
Homework Answers
Soluble Impurities :- Soluble Impurities are those Impurities which are soluble in the sample and get disappeared when added into sample , Few examples are sugar , salt.
Effect of Soluble Impurities on the melting point :- Soluble impurities decreases melting point of the sample . It is because it gets dissolve in the sample and interacts with its atoms , which will decrease the strength of the lattice of sample , and thus decreases the melting point.
Insoluble Impurities :- These are those impurities which are insoluble in the sample , and gets separated when added to the sample , Examples are Charcoal, mud etc
Effect of Insoluble Impurities on the melting point :- Insoluble Impurities do not affect the melting point of the solution , as it gets separated from the sample, and thus do not interact with the atoms of the sample , thus the lattice of the sample will remain affected due to the insoluble impurities .
Hope it helps.

Hexachlorobenzene has a literature melting point of 231 ºC. What would be a reasonable result when melting an impure sample of hexachlorobenzene? It would start melting around 229 ºC and finish melting around 233 ºC. It would start melting around 225 ºC, and finish melting around 230º C. The impurity would melt at whatever temperature is normal for that impurity, but the hexachlorobenzene would melt right at 231 ºC . It would melt right at a temperature lower than the...
