How does a lead-acid battery work?
The chemical reaction in a lead-acid battery places two electrons on the anode and removes two from the cathode. It requires a closed circuit to proceed, since the two electrons must be supplied to the cathode. The amount of resistance to the flow of current within the voltage source is called the internal resistance.
What is a lead acid battery?
The lead acid battery used in cars and other vehicles is one of the most common combinations of chemicals. Figure 6.1.3 shows a single cell (one of six) of this battery. The cathode (positive) terminal of the cell is connected to a lead oxide plate, whereas the anode (negative) terminal is connected to a lead plate.
What is electromotive force?
According to the IUPAC convention, the electromotive force is the potential of the right hand electrode referred to the potential of the left hand electrode. We consider, for example, a hydrogen-oxygen cell shown in Fig. 6-4; the cell reaction is given by Eqn. 6-1 and the cell diagram is given by Eqn. 6-5: Fig. 6-4.
How does electric potential affect EMF of a battery?
Figure 6.1.7 A graph of the voltage through the circuit of a battery and a load resistance. The electric potential increases the emf of the battery due to the chemical reactions doing work on the charges. There is a decrease in the electric potential in the battery due to the internal resistance.
How do you write electromotive force in chemistry?
The electromotive force is then expressed in Eqn. 6-8: ,where E H 2 /O 2 0 is the standard electromotive force (1.23 V at 25°C) and p is the fugacity of hydrogen and oxygen gases. In general, the cell reaction may be written in Eqn. 6-9:
Which electrolyte is used in a lead-acid cell?
Both plates are immersed in sulfuric acid, the electrolyte for the system. Figure 6.1.3 Chemical reactions in a lead-acid cell separate charge, sending negative charge to the anode, which is connected to the lead plates.
