Why NaOH is used in titration?

Sodium hydroxide is used in titration if the unknown sample solution is acidic because bases are used to neutralize acids.

Why do we use NaOH?

Sodium hydroxide is useful for its ability to alter fats. It is used to make soap and as a main ingredient in household products such as liquid drain cleaners. Sodium hydroxide is usually sold in pure form as white pellets or as a solution in 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.

What is end point in titration?

end point: the point during a titration when an indicator shows that the amount of reactant necessary for a complete reaction has been added to a solution.

Is sodium hydroxide a strong base?

Strong bases A strong base is something like sodium hydroxide or potassium hydroxide which is fully ionic. You can think of the compound as being 100\% split up into metal ions and hydroxide ions in solution.

Does sodium hydroxide lower pH?

The hydroxide ions from dissolved sodium hydroxide perturb this balance; as the additional hydroxides accept protons from hydronium ions, they decrease the hydrogen ion concentration, thereby increasing the pH. Adding more sodium hydroxide will increase the pH of the water or make it more basic.

Why is NaOH a good secondary standard?

It attracts water vapour from atmosphere. Take a solution of NaOH and measure the mark you will see the volume rises up after some time and gets above the mark. Becoming more dilute. Thus NaOH changes concentration with time hence a secondary standard solution.

Why is NaOH not a primary solution?

Such acid–base reactions can also be used for titrations. However, sodium hydroxide is not used as a primary standard because it is hygroscopic and absorbs carbon dioxide from air.

What is difference between endpoint and equivalence point?

The main difference between equivalence and endpoint is that the equivalence point is a point where the chemical reaction comes to an end while the endpoint is the point where the colour change occurs in a system.

What is endpoint and equivalence point?

Equivalence point represents the stage of titration where the concentrations of titrate and titrant are chemically equivalent. An endpoint represents the stage of titration that indicates the completion of the titration with the help of the change in colour or intensity of the solution.
