What are the reduction potentials of lithium, sodium and potassium?

To find the reduction potentials of lithium, sodium, and potassium, you can refer to a standard reduction potential table, often referred to as an electrochemical series or a standard electrode potential table.
1. Start by searching for a reliable source for an electrochemical series table. Good sources include chemistry textbooks, online databases, or even websites of educational institutions.
2. Look for the specific entry related to the metals of interest: lithium (Li), sodium (Na), and potassium (K). The reduction potentials are typically given in volts (V) relative to the standard hydrogen electrode (SHE).
3. The reduction potentials for lithium, sodium, and potassium will indicate the tendency of each metal to gain electrons and undergo reduction. The more positive the value, the stronger the tendency to be reduced. Additionally, the values can serve as an indicator of the relative reactivity or oxidation potential of each metal.
Remember that the values obtained from the table will represent standard reduction potentials under specific conditions. The exact values may vary depending on factors such as temperature, concentration, and pH.
The reduction potentials of lithium (Li), sodium (Na), and potassium (K) can be found in standard reduction potential tables. Here are the reduction potentials for each element at standard conditions (25°C and 1 atmosphere of pressure):
1. Lithium (Li): -3.04 V
2. Sodium (Na): -2.71 V
3. Potassium (K): -2.93 V
These values represent the tendency for each metal to undergo reduction (gain electrons) in a redox reaction. A more negative reduction potential indicates a stronger tendency to be reduced.
