How do you make a 2N sodium hydroxide solution?

Procedure

1. Weigh 40 g NaOH and add to a clean 500 ml bottle.
2. Add 500 ml DI water and a stir bar. Stir on a stir plate for 30 minutes or until solids are dissolved.
3. Label the container with the contents, date and a batch number.
4. Store the closed container at room temperature for up to one year.

What is the role of NaOH in titration?

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

Which indicator is used for titration of NaOH and HCL?

phenolphthalein
For a weak acid vs strong alkali titration, phenolphthalein is the most suitable indicator. This is so because the last drop of added alkali brings the pH of the solution in the range in which phenolphthalein shows sharp colour change.

What is 2N solution?

Normality is a measure of concentration that is equal to the gram equivalent weight of solute per litre of solution. Gram equivalent weight is a measure of the reactive capacity of a molecule*. Unit of normality is Eq/L. For chloride ions, the normality is 2N because 1M of calcium chloride yields 2M of chloride ions.

How do you prepare PH for NaOH solution?

Requirements

1. Step 1: To prepare 100 ml of 10 M NaOH solution, weigh out 40 g of NaOH (molecular weight: 40).
2. Step 2: Dissolve NaOH pellets in 70 ml water by adding small quantities of NaOH in the water.
3. Step 3: Adjust the solution volume to 100 ml with deionized/double distilled water.
4. 50 ml.
5. 100 ml.
6. 250 ml.
7. 500 ml.
8. 1 M.

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.

What is titration used for in chemistry?

titration, process of chemical analysis in which the quantity of some constituent of a sample is determined by adding to the measured sample an exactly known quantity of another substance with which the desired constituent reacts in a definite, known proportion.

What is the suitable indicator for titration of NaOH and oxalic acid?

Hence, the indicator used for the titration of oxalic acid with sodium hydroxide is phenolphthalein.

Is sodium hydroxide an indicator?

Phenolphthalein is an indicator of acids (colorless) and bases (pink). Sodium hydroxide is a base, and it was in the pitcher at the beginning, so when added to the phenolphthalein in beakers 2 and 4, it turned pink (top half of the graphic)….
