- Q1. Principal ofHPLC
- Ans.
HPLC is a technique used to separate, identify, and quantify components in a mixture based on their interactions with a stationary phase and a mobile phase.
HPLC involves pumping a sample mixture through a column packed with a stationary phase, where different components interact differently and are separated based on their affinity for the stationary phase.
The separated components are detected as they exit the column a...
- Q2. Formula of acid
- Ans.
The formula for an acid is typically written as HX, where X represents an anion.
Acids are substances that donate protons (H+ ions) in a chemical reaction
The general formula for an acid is HX, where H represents a hydrogen ion and X represents an anion
Examples include HCl (hydrochloric acid), H2SO4 (sulfuric acid), and HNO3 (nitric acid)

- Q1. What is acidity?
- Ans.
Acidity is the measure of the concentration of hydrogen ions in a solution.
Acidity is measured on the pH scale, which ranges from 0 to 14.
A pH of 7 is neutral, while a pH below 7 is acidic and above 7 is basic.
Acidity can affect the properties and behavior of substances, such as their solubility and reactivity.
Examples of acidic substances include vinegar, lemon juice, and battery acid.
- Q2. Where are using indicators?
- Ans.
Indicators are used in quality control to determine the endpoint of a reaction or to indicate the presence of a specific substance.
Indicators are used in titrations to determine the endpoint of a reaction.
They can also be used to indicate the presence of a specific substance in a sample.
Common indicators include litmus paper, phenolphthalein, and methyl orange.
Indicators can be organic compounds or inorganic compounds.

- Q3. Indicators types?
- Q4. What is titration & using these solution?
- Ans.
Titration is a technique used to determine the concentration of a solution by reacting it with a solution of known concentration.
Titration involves adding a solution of known concentration (the titrant) to a solution of unknown concentration until a reaction is complete.
The point at which the reaction is complete is called the endpoint.
The endpoint is usually detected using an indicator, which changes color when the re...

- Q1. What is ph. How to find the ph.
- Ans.
pH is a measure of acidity or basicity of a solution. It is the negative logarithm of hydrogen ion concentration.
pH ranges from 0 to 14, with 7 being neutral
Acidic solutions have a pH less than 7, while basic solutions have a pH greater than 7
pH can be measured using a pH meter or pH paper
pH can also be calculated using the formula pH = -log[H+], where [H+] is the hydrogen ion concentration

- Q1. What is distillation ?
- Ans.
Distillation is a process of separating components of a mixture based on their boiling points.
It involves heating the mixture to vaporize the component with the lowest boiling point.
The vapor is then condensed and collected as a separate liquid.
This process can be used to purify liquids, separate different components of a mixture, and extract essential oils from plants.
Examples include the distillation of alcohol to ma...
