To Control Ionization. 1  Ionization Voltage Typically, 70eV electrons from the filament are used for EI. 2  Emission Current The number of ions produced in unit time is proportional to the current of emitted electrons, i.e., emission current. 3  Ion Source Temperature The ion source is usually used at about 200 oC.
If the voltage of a ZnâH + cell (like that in Figure 20.11) is 0.45 V at 25Â°C when [Zn 2+] = 1.0 M and P H 2 = 1.0 atm, what is the concentration of H +? SOLUTION The cell reaction is The standard emf is EÂ° = +0.76 V.
