Question

How do you solve the titration process step by step?

Answer 1

First of all we should be aware of the titration process. Titration is the process or a technique to determine the concentration of an unknown solution, with the use of a solution of known concentration. The concentration of an unknown solution is determined only by knowing the volume of titrant used.

Complete step-by-step answer:
The basic principle of titration is that – When a solution called a standard solution or titrant is added to a sample which, we have to analyze.
Titration process step by step:-

First of all we should determine ${\left[ {OH} \right]^ - }$

After that we have to determine the number of moles of ${\left[ {OH} \right]^ - }$ by using the formula
$No.\,\,of\,moles = \,Molarity \times \,Volume$

Then we have to determine the number of moles of ${H^ + }$
When the base neutralizes the acid, then the $no.\,\,of\,moles\,of\,{H^ + } = \,\,no.\,\,of\,moles\,of\,O{H^ - }$
After that we have to determine the concentration of HCl l
Since, every moles of HCl will produce one mole of ${H^ + }$
Therefore, $no.\,\,of\,moles\,of\,HCl = \,\,no.\,\,of\,moles\,of\,{H^ + }$
Thus, $Molarity = \dfrac{{No.\,\,of\,moles}}{{Volume}}$

Phenolphthalein acts as a good indicator for the titration process. The pH range of phenolphthalein generally lies between - 8.3 to 10, thus making it a good indicator for the titration process. This is because the titration’s graph falls sharply at the equivalence point made by the phenolphthalein.
Equivalence point in titration means that the amount of titrant is just enough to completely neutralize the analyte solution.

Note: The purpose of titration is that it is the detection of the equivalence point, or the point at which the chemically equivalent amount of the reactants have been mixed. The amount of reactants which have been mixed at the equivalence point generally depends on the stoichiometry of the reaction.
