  • Q1. Basic knowledge of chemistry subject
  • Q2. What is ph and it's range
  • Ans. 

    pH is a measure of acidity or alkalinity in a solution, ranging from 0 to 14.

    • pH stands for 'potential of hydrogen'

    • It measures the concentration of hydrogen ions in a solution

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

    • The pH scale is logarithmic, meaning each unit represents a tenfold difference in acidity or alkalinity

    • Examples: lemon juice has a pH of around 2, water has a pH of 7, and b

  • Q3. What is titrations
  • Ans. 

    Titrations is a laboratory technique used to determine the concentration of a substance in a solution.

    • It involves adding a known amount of a solution of known concentration to a solution of unknown concentration until a reaction is complete.

    • The point at which the reaction is complete is called the endpoint.

    • The amount of the known solution added is used to calculate the concentration of the unknown solution.
