In an ionic compound, the size of the ions affects the internuclear distance (the distance between the centers of adjacent ions), which affects lattice energy (a measure of the attractive force holding those ions together).
It is often useful to be able to anticipate, without doing a detailed calulation, whether an increase in temperature will result in a raising or a lowering of a reaction enthalpy.
If the following substance is dissolved in pure water, will the solution be acidic and Explain Ammonium sulfate-((NH4)2SO4)
