Solutions are classified into acids or bases based on the pH value.
Titration is a process where a known concentrated solution is used for determining the concentration of an unknown solution. Solution of a known concentration is called as titrant while solution of an unknown concentrated is called as an analyte.
pH is a measure of hydrogen ion present in a solution.It is the negative logarithm of the H+ concentration to the base 10. It gives the acidic strength to a solution.
Acid: Acid substance is the one which can donate a proton or accept a pair of electron.
Base: Base substance is the one which can accept a proton or donate a pair of electrons.
Solutions are classified into acids or bases based on the pH value. If pH value is less than 7, the solution is acidic, and if pH is greater than 7, the solution is basic.
pH of a solution can be determined by identifying the concentration of in the solution.
The value is negative logarithm (base) of the Hydrogen ion concentration.
Molarity: Molarity is the ratio of the number of moles to the volume of the solution.

Learning Goal: To learn about titration types and how to calculate pH at different points of titration. In an acid-base titration, a titrant (solution of a base or acid) is added slowly to an analyte (solution of an acid or base). The titration is often monitored using a pH meter. A plot of pH as a function of the volume of titrant added is called a pH titration curve. Prior to the titration, the pH is determined by the concentration...
