Introduction
Determination of chemic pull of HCl is of import for textile industry. It he pull of HCl is non proper hence the every procedure on stuff is non proper. Titration is the best method for decision of pull of HCl. In this method 0.1 due north NaOH is used for titration.
 |
| Strength examination of HCl |
- To know virtually how determined the pull of HCl.
- To know virtually the titration process.
- To know virtually the solution making.
- To know virtually the destination betoken of this testing.
- Beaker
- Pipette
- Stirrer
- Graduate cylinder
- Electronic residual
- Burette
- HCl
- 0.1 due north NaOH
- And Indicator ( Phenolphthalein)
4 ml HCl is taken
↓
Then it is diluted amongst 500 ml H2O ↓
From that solution 25 ml is taken
↓
After that 2-3 drops of indicator is added ↓
Then it is taken inwards Conical flask. Then this sample solution is treated amongst 0.1 due north NaOH
End Point: The destination betoken is determined when the permanent pinkish color solution stay.
Calculation for Result
Molecular equivalent weight of HCl = 36.5 gm
So, one 1000 ml Molecular equivalent weight is 36.5
1 ml molecular equivalent weight is = 36.5/1000 = 0.0365 gm
In 500 ml H2O the total of sample is iv ml
So, 25 ml of H2O the total of sample is = ( iv X 25)/500 = 0.20
Normality of NaOH is 0.1 due north
And book used of KMnO4 is 24.5 & 25.6
 |
Required Amount of NaOH | Strength of HCl % |
24.5 & 24.6 | 44.712 & 44.895 |
23.7 & 22.3 | 43.252 & 40.697 |
24 & 23.2 | 43.8 & 42.34 |
23.8 & 24.1 | 43.435 & 43.982 |
23.7 & 23.5 | 43.252 & 42.887 |
From inwards a higher house results, nosotros tin tell that the pull of HCl of dissimilar persons results direct maintain been obtained close to 43.5% as well as my results is 44.712 & 44.895 . nosotros direct maintain done experiment manually hence something tin live inaccurate mensuration of pipette or burette reading. And at last, nosotros tin tell that the pull of HCl is 44 %.
Conclusion
At final nosotros tin tell that, how to gain upwards one's hear the pull of HCl, is known past times this experiment. Knowledge is gained from this experiment which is real helpful inwards our practical life.
