Critical Soln. Temperature
“upper consolute temp.”
Tie the ampoule with a thread
If the difference between the temp. at which turbidity disappears and re-appears is > 2ºC, heat again and record the temp. at which turbidity disappears again.
Suspend the amp. So that the contents of the ampoule must be completely immersed in the water bath
Record the temperature at which the turbidity disappears (T1) using a thermometer
In a beaker put water to form water bath
Heat WB gradually with continuous shaking of the amp up & down
Turn off the flame and record the temperature at which turbidity re-appears (T2)
1- Be very cautious with the ampoule (phenol injury is 3rd degree burn).
2- Suspended ampoule must not touch the wall or bottom of the beaker.
3- when recording the temperature, the suspended thermometer must not touch the wall or bottom of the beaker.
4- If the difference between the temp. at which turbidity disappears and re-appears is > 2ºC, heat again and record the temp. at which turbidity disappears again.
