Succinic acid, a white solid that melts at 182°C, is heated gently, and a gas is given off. After the gas evolution stops, a whi
te solid remains that melts at a temperature different from 182°C. In terms of the number of atoms contained, how do you thing the size of succinic acid molecules compares with the size of the molecules of the white solid produced by this process?
In terms of the size, we can infer from the discussion that the succinic acid will now have a lower size after it has given off the gas. The lower size implies a decrease in the number of atoms that would be contained in the acid. The gas given off has a particular number of atoms it will carry off during its emission.
We can conclude that succinic acid will have more atoms and a larger size compared to the white solid that results from the heating process.
The substance that releases the greatest amount of ions will have the greatest attractive forces within its solution, resulting in a reduced freezing point. K₂SO₄ yields 3 ions NH₄I yields 2 ions CoCl₃ yields 4 ions
