- Q2. What is normality
- Ans.
Normality is a measure of concentration in chemistry, expressed as the number of equivalents of a solute per liter of solution.
Normality is similar to molarity, but takes into account the number of equivalents of a solute rather than just the number of moles.
It is calculated by dividing the number of equivalents of solute by the volume of solution in liters.
For example, a 1M solution of HCl is also 1N, since HCl is a m

- Q1. What is tha pH?
- Ans.
pH is a measure of the acidity or alkalinity of a solution.
pH stands for 'potential of hydrogen'.
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 determined by the concentration of hydrogen ions in a solution.
Examples: Lemon juice has a pH of around 2, while baking soda has a pH of around 9.
- 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.
- Ans.
LOD stands for Limit of Detection. It is the lowest concentration of a substance that can be reliably detected.
LOD is used to determine the sensitivity of an analytical method.
It is usually expressed as a concentration or mass.
Water is a chemical compound composed of hydrogen and oxygen, while LOD is a term used in analytical chemistry.
LOD is important in environmental testing to determine the presence of contaminants ...
- Q4. Lod is loss on drying to determine the volatile impurities and the water is dtermination of presens of moisture and water molecules in sample
