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

• Calib...read more

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.

pH is a measure of acidity or alkalinity of a solution. It is measured on a scale of 0 to 14.

• pH stands for 'potential of Hydrogen'

• It is a measure of the concentration of hydrogen ions in a solution

• A pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline

• pH can be measured using pH meters, pH paper/strips, or pH indicators

Calibration ensures accuracy of instruments by comparing measurements to a known standard.

• Calibration is the process of adjusting an instrument to ensure its measurements are accurate.

• Principles of instruments include accuracy, precision, repeatability, and reproducibility.

• Examples of calibrated instruments include thermometers, scales, and pressure gauges.

Investigation tools are used to analyze data and identify issues in software development.

• Common investigation tools include debuggers, profilers, and log analyzers.

• Debuggers help identify and fix coding errors by allowing developers to step through code and inspect variables.

• Profilers analyze the performance of code, identifying bottlenecks and areas for optimization.

• Log analyzers parse and analyze log files to identif...read more
