Expand the term PPP. What is the use of PPP?
Show Hint
especially for point-to-point links like dial-up and broadband.
Solution and Explanation
It is a communication protocol used to establish
a direct connection between two network nodes.
PPP is widely used for internet connections
over dial-up modems, leased lines, and DSL links.
It provides features like authentication, encryption,
and data compression for secure and reliable communication.

Standard electrode potential for \( \text{Sn}^{4+}/\text{Sn}^{2+} \) couple is +0.15 V and that for the \( \text{Cr}^{3+}/\text{Cr} \) couple is -0.74 V. The two couples in their standard states are connected to make a cell. The cell potential will be:
To calculate the cell potential (\( E^\circ_{\text{cell}} \)), we use the standard electrode potentials of the given redox couples.
Given data:
\( E^\circ_{\text{Sn}^{4+}/\text{Sn}^{2+}} = +0.15V \)
\( E^\circ_{\text{Cr}^{3+}/\text{Cr}} = -0.74V \)- CBSE CLASS XII - 2025
