UV spectrophotometer principle and calibration
UV spectrophotometer measures the absorbance or transmittance of light in the UV range
Principle: It uses a UV light source to pass light through a sample and measures the intensity of light before and after passing through the sample
Calibration: Involves setting the instrument to zero absorbance with a blank solution and verifying accuracy with known standard solutions

pH stands for potential of hydrogen.
pH is a measure of the acidity or alkalinity of a solution.
It is a logarithmic scale ranging from 0 to 14.
A pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline.
pH is commonly used in various fields such as chemistry, biology, and environmental science.
The aufbau principle is a rule in quantum mechanics that states how electrons fill atomic orbitals.
The principle states that electrons fill the lowest energy levels first before moving to higher energy levels.
It follows the order of filling orbitals: 1s, 2s, 2p, 3s, 3p, 4s, etc.
Each orbital can hold a maximum of two electrons with opposite spins.
For example, the electron configuration of carbon (atomic number 6) is 1s²
Electron pairing occurs after half-filled orbitals in a subshell.
Electron pairing is a phenomenon where two electrons occupy the same orbital.
This occurs after each orbital in a subshell has been half-filled with electrons.
The pairing of electrons is due to the principle of maximum multiplicity.
For example, in the p subshell, electron pairing occurs after the first three orbitals have been half-filled with electrons.
