The temperature of the ionosphere ranges from about 200K, or -73 ÂºC (-99.4 ÂºF) to 500K, or 227 ÂºC (440.6 ÂºF).So basically at the bottom it is 200K. At the top it is 500K.K is in Kelvin.he temperature of the ionosphere ranges from about 200K, or -73 ÂºC (-99.4 ÂºF) to 500K, or 227 ÂºC (440.6 ÂºF). So basically at the bottom it is 200K.

Generally the conductivity of a solution increases with temperature, as the mobility of the ions increases. For comparison purposes reference values are reported at an agreed temperature, usually 298 K (~25 C), although occasionally 20C is used.he concentration of ions in a solution of a weak electrolyte is less than the concentration of the electrolyte itself. For acids and bases the concentrations can be calculated when the value(s) of the acid dissociation constant (s) is(are) known.
