- Q1. What is molarity
- Ans.
Molarity is a measure of the concentration of a solution expressed as the number of moles of solute per liter of solution.
Molarity is calculated by dividing the number of moles of solute by the volume of the solution in liters.
It is denoted by the symbol 'M'.
Molarity is commonly used in chemistry to express the concentration of a solution.
For example, a 1 M solution of sodium chloride contains 1 mole of sodium chloride

- Q2. Explain about pH activity
- Ans.
pH activity refers to the measurement of acidity or alkalinity of a solution.
pH activity is measured on a scale of 0-14, with 7 being neutral, below 7 being acidic, and above 7 being alkaline
It is important in various fields such as chemistry, biology, and environmental science
For example, pH activity is used to determine the acidity of soil for agriculture, the pH of water for aquatic life, and the pH of blood for med
- Q3. Why if adding acid pH value get decreasing and adding alkali pH value is increasing
- Ans.
The pH value decreases when acid is added and increases when alkali is added.
Acids release hydrogen ions (H+) when dissolved in water, which increases the concentration of H+ ions and lowers the pH value.
Alkalis release hydroxide ions (OH-) when dissolved in water, which decreases the concentration of H+ ions and raises the pH value.
The pH scale ranges from 0 to 14, with 7 being neutral. Values below 7 are acidic, and ...
- Q4. Write a chemical reaction
- Ans.
Chemical reaction between sodium and chlorine
Sodium (Na) reacts with chlorine (Cl) to form sodium chloride (NaCl)
The reaction is exothermic and releases energy in the form of heat and light
The balanced chemical equation is 2Na + Cl2 -> 2NaCl

- Q1. What is PCR and it's types
- Q2. What is chromatography
- Ans.
Chromatography is a laboratory technique used to separate mixtures into their individual components.
Chromatography involves a stationary phase and a mobile phase
The components of the mixture interact differently with the stationary phase, leading to separation
Common types include gas chromatography, liquid chromatography, and thin-layer chromatography
- Q3. What is gram positive and negative bacteria
- Q4. What is depth filtration
- Ans.
Depth filtration is a filtration method where particles are captured within the thickness of the filter medium.
Depth filtration involves particles being trapped within the filter matrix rather than just on the surface.
It is commonly used in industries such as pharmaceuticals, food and beverage, and water treatment.
Examples of depth filtration media include sand filters, activated carbon filters, and diatomaceous earth

- Q1. Why flow-through is collected during AEX chromatography?
- Ans.
Flow-through is collected during AEX chromatography to separate unbound molecules from the target molecule bound to the resin.
Flow-through contains molecules that did not bind to the resin
Target molecule is retained on the resin due to interactions with the stationary phase
Flow-through is collected to isolate the target molecule for further analysis
- Q2. What is Ion Exchange Chromatography?
- Ans.
Ion exchange chromatography is a technique used to separate and purify proteins and other charged molecules based on their net charge.
Separates molecules based on their charge
Uses a stationary phase with charged groups to attract and bind charged molecules
Elution is achieved by changing the ionic strength or pH of the mobile phase
Commonly used in protein purification and analysis
