How can we add more solute to a saturated solution, other than increasing the temperature?
Physical Chemistry
A beaker is half filled with water. A thermometer is placed in the water and the temperature is notes to be 25°C. The beaker is placed on a tripod and, instead of using a Bunsen Burner, a spirit burner filled with ethanol, C2H5OH, is lit and placed underneath the beaker.
a)Why can the ethanol be used as a fuel in the spirit burner?
b)After about ten minutes, the reading on the thermometer is checked. What should one observe?
