What are the hazardous properties of sodium hydroxide?

Contact with very high concentrations of sodium hydroxide can cause severe burns to the eyes, skin, digestive system or lungs, resulting in permanent damage or death. Prolonged or repeated skin contact may cause dermatitis. Repeated inhalation of sodium hydroxide vapor can lead to permanent lung damage.

What is the CAS number for potassium hydroxide?

Key Spec Table

CAS # EC Number Chemical Formula
1310-58-3 215-181-3 KOH

How will you prepare sodium hydroxide give its properties and uses?

Method of prepration of sodium hydroxide A brine solution is electrolyzed using mercury cathode and carbon anode. Sodium metal, discharged at the cathode, combine with mercury to form sodium amalgam. Cl gas is evolved at the cathode. The amalgam is treated with water to give sodium hydroxide and hydrogen gas.

What is the pH value of sodium hydroxide?

The pH of a solution of sodium hydroxide is 9.

How do I find my CAS number for chemicals?

To find the CAS number of a compound given its name, formula or structure, the following free resources can be used:

  1. NLM,NIH ChemIDplus.
  2. NIST Chemistry WebBook.
  3. NCI/CADD Chemical Identifier Resolver.
  4. ChemSub Online (Multilingual chemical names)
  5. NIOSH Pocket Guide to Chemical Hazards, index of CAS numbers.

Does water have a CAS number?

Water CAS 7732-18-5 | 101262.

What is the difference between KOH and NaOH?

Potassium hydroxide and sodium hydroxide are strong bases. Both are hydroxides of alkali metals. The main difference between Potassium hydroxide and Sodium Hydroxide is that Potassium hydroxide has a potassium cation and a -OH anion whereas Sodium Hydroxide has a sodium cation and –OH anion.

Which property is shown by the alkali sodium hydroxide?

Physical properties. Pure sodium hydroxide is a colorless crystalline solid that melts at 318 °C (604 °F) without decomposition, and with a boiling point of 1,388 °C (2,530 °F). It is highly soluble in water, with a lower solubility in polar solvents such as ethanol and methanol.

What is the pH of 0.1 NaOH solution?

Hence, the pH of 0.1 M NaOH is 13.

Is sodium hydroxide a strong base?

Because sodium hydroxide is a strong base that dissociates completely in solution to form hydroxide ions, if the concentration of hydroxide ions in solution is .

Which placard is required for sodium hydroxide?

UN 1824
Placard – UN 1824 Sodium Hydroxide, Tagboard.

What are the health hazards of sodium hydroxide?

– Owing to its poisonous affects, it can also cause bleeding, vomiting, and diarrhea. – Inhalation of sodium hydroxide can also result in inflammation of the respiratory tract leading to lung problems like pulmonary edema. – Fever, sneezing, runny nose, sore throat, and pneumonia are some of the severe consequences of coming in contact with this chemical.

Is sodium hydroxide a stronger base than calcium hydroxide?

Sodium hydroxide is a strong base. Aqueous solutions of ammonia are weak bases. The stronger base is sodium hydroxide. Note that the difference in pH could be caused by the sodium hydroxide solution being quite dilute while the ammonia solution could be quite concentrated.

Is sodium hydroxide and caustic soda the same thing?

Sodium hydroxide, lye, and caustic soda all refer to the same compound, NaOH, which is comprised of 3 single atoms: sodium, oxygen, and hydrogen. NaOH is often used to teach about pH in high schools and it can neutralize HCl. Using some simple supplies, you can make homemade NaOH for use in the lab, or just to impress your colleagues and students.

Is sodium hydroxide considered a stable chemical?

Sodium hydroxide is considered stable in normal conditions of use. NaOH is incompatible with the metals aluminum, tin, and zinc, as well as their alloys, and the reaction with these metals can drive the production of flammable and potentially explosive hydrogen gas and should be avoided.
