- Q1. What is pH principal
- Ans.
pH is a measure of the acidity or alkalinity of a solution on a scale of 0 to 14.
pH stands for 'potential of Hydrogen'
It indicates 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 is important in various industries such as food, pharmaceuticals, and environmental monitoring
- Q2. What is HPLC principal
- Ans.
HPLC stands for High Performance Liquid Chromatography, a technique used to separate, identify, and quantify components in a mixture.
HPLC involves passing a liquid sample through a column filled with a stationary phase, where different components in the sample interact differently with the stationary phase and elute at different times.

- Q2. PH presens of hydrogen in sample .
- Ans.
PH represents the concentration of hydrogen ions in a sample.
PH is measured on a scale of 0-14, with 7 being neutral.
A lower PH indicates higher acidity, while a higher PH indicates higher alkalinity.
PH can be measured using a PH meter or through chemical indicators.
The PH of a sample can affect its chemical properties and reactions.
- Q3. What is lod and difference between lod and water.
