What is pH of 10\% NaOH?

13
Hence, the pH of N/10 sodium hydroxide is 13.

How do you make a 10 n NaOH solution?

Therefore, 4 g of NaOH dissolved in one litre of solution will give N/10 NaOH solution. Weigh quickly 4 g NaOH in a beaker (as it is hygroscopic) and dissolve it in distilled water (preferably CO -free). Transfer the contents and the washings to a volumetric flask (1 litre). Cool and then make volume up to the mark.

What is normality of 10 NaOH solution?

2.5
Normality and molarity of sodium hydroxide are the same. The normality of 10\% is 2.5 so, in theory at least, diluting it 25 times should render a normality of 0.1N.

Is sodium hydroxide gas?

At room temperature, sodium hydroxide is a white, odorless solid. Liquid sodium hydroxide is colorless and has no odor. It can react violently with strong acids and with water. Sodium hydroxide is corrosive.

How do you make a 10 caustic solution?

The preparation of 10 N NaOH involves a highly exothermic reaction, which can cause breakage of glass containers. Prepare this solution with extreme care in plastic beakers. To 800 mL of H2O, slowly add 400 g of NaOH pellets, stirring continuously. As an added precaution, place the beaker on ice.

How do you calculate normality example?

Normality Formula

  1. Normality = Number of gram equivalents × [volume of solution in litres]-1
  2. Number of gram equivalents = weight of solute × [Equivalent weight of solute]-1
  3. N = Weight of Solute (gram) × [Equivalent weight × Volume (L)]
  4. N = Molarity × Molar mass × [Equivalent mass]-1

What happens if you drink Naoh?

Sodium hydroxide is a potentially dangerous substance. It can hurt you if it touches your skin, if you drink it or if you breathe it. Eating or drinking sodium hydroxide can cause severe burns and immediate vomiting, nausea, diarrhea or chest and stomach pain, as well as swallowing difficulties.

How do you make NaOH at home?

Dissolve 1 tablespoon (17 grams) of salt in 1.24 cups (290 mL) of water. Add the water to a glass and gently pour the salt into the water. Stir it in well with a spoon until the salt is completely dissolved. If your cup has a lid, attach it after adding the salt and shake it up and down to mix the salt it in.
