Question

g When water and perchloric acid (HClO4) are mixed, heat is released. The resulting solution is not an ideal solution, in terms of Raoult’s Law. How should the boiling point and the vapor pressure of a solution of HClO4 in H2O differ from what is expected for an ideal solution? A) boiling point higher than expected, vapor pressure lower than expected B) boiling point higher than expected, vapor pressure higher than expected C) boiling point lower than expected, vapor pressure lower than expected D) boiling point lower than expected, vapor pressure higher than expected E) boiling point and vapor pressure are both the same as expected for an ideal solution

Answer 1

Answer:

A) boiling point higher than expected vapor pressure lower than expected.

Explanation:

When water is introduced with heat it vaporize at a temperature of 100 degree centigrade. When hydrochloric acid is added to the water its boiling point of water increases slightly. The difference in the boiling point is due to the presence of heavier molecules in acid.
