How is sodium chloride prepared by titration?
For example, if we need to prepare sodium chloride, we need to use the titration method. This is because sodium chloride is a soluble salt and it is a Group I salt. To prepare sodium chloride, we need to react hydrochloric acid with sodium hydroxide to form sodium chloride and water.
Why is HCl and NaOH used in titration?
During the course of the titration, the titrant (NaOH) is added slowly to the unknown solution. As it is added, the HCl is slowly reacted away. The point at which exactly enough titrant (NaOH) has been added to react with all of the analyte (HCl) is called the equivalence point.
How is titration performed?
The process is usually carried out by gradually adding a standard solution (i.e., a solution of known concentration) of titrating reagent, or titrant, from a burette, essentially a long, graduated measuring tube with a stopcock and a delivery tube at its lower end.
What is the reaction of sodium hydroxide and hydrochloric acid?
NaOH(aq)+HCl(aq)→NaCl(aq)+H2O(l)
Which salt is best prepared by titration method?
If there’s a change in pH, color or conductivity that allows for detection of a titration endpoint. Out of the choices, barium sulfate best meets these conditions.
How do you make salts with titration?
Method
- Use the pipette and pipette filler to add 25 cm 3 of alkali to a clean conical flask.
- Add a few drops of indicator and put the conical flask on a white tile.
- Fill the burette with acid and note the starting volume.
- Slowly add the acid from the burette to the alkali in the conical flask, swirling to mix.
How do you make sodium hydroxide solution for titration?
Sodium Hydroxide Solution Preparation
- Take about 100ml of distilled water in a cleaned and dried 1000 ml volumetric flask.
- Add about 4.2 gm of Sodium hydroxide with continues stirring.
- Add more about 700ml of distilled water, mix and allow to cool to room temperature.
- Make up the volume 1000 ml with distilled water.
