What are physical properties of 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 specific gravity of 50 sodium hydroxide?
Properties of Caustic Soda Solutions based on international critical tables volume 3 page 79
| NaOH | Freeze Point | Specific Gravity |
|---|---|---|
| 25% | 0 | 1.278 |
| 30% | 36 | 1.332 |
| 40% | 60 | 1.434 |
| 50% | 58 | 1.530 |
Is sodium hydroxide a base or acid?
Sodium hydroxide is completely ionic, containing sodium ions and hydroxide ions. The hydroxide ion makes sodium hydroxide a strong base which reacts with acids to form water and the corresponding salts, e.g., with hydrochloric acid, sodium chloride is formed: NaOH( aq) + HCl(aq) → NaCl(aq) + H2O( l)
Is sodium hydroxide a good conductor of electricity?
In solid state, sodium hydroxide cannot conduct electricity as the ions are not free to move. They are tightly packed in the crystal lattice and are localized. At the best, they can vibrate around their mean position. Since there is no movement of ions, there is no electrical conductivity in solid sodium hydroxide.
How would you prepare a 50 sodium hydroxide solution?
Stock solution, 50% (by weight): Add 100 mL of distilled water to 100 g of reagent grade sodium hydroxide (NaOH) pellets and stir until solution is complete.
What type of acid is sodium hydroxide?
sodium compounds Sodium hydroxide (NaOH) is a corrosive white crystalline solid that readily absorbs moisture until it dissolves. Commonly called caustic soda, or lye, sodium hydroxide is the most widely used industrial alkali. It is highly corrosive to animal and vegetable tissue. The alkaline solutions it forms…
Is lye a base or acid?
Now let’s look at lye, a strong base with the chemical formula NaOH (sodium hydroxide). If we add NaOH to water, it dissociates into Na+ and OH-.
Is glucose a good conductor of electricity?
Glucose (sugar) readily dissolves in water, but because it does not dissociate into ions in solution, it is considered a nonelectrolyte; solutions containing glucose do not, therefore, conduct electricity.
What are the chemical properties of sodium hydroxide?
Chemical Properties of Sodium Hydroxide It has an ionic bond. It can react with protic acids to form water and salts. It has high acidity of 13.
What happens when sodium hydroxide is mixed with water?
Sodium Hydroxide in its pure form is a white crystalline solid. It is odourless. It is soluble in water, glycerol and ethanol. When solid sodium hydroxide is mixed with water it results in a highly exothermic reaction. Has a higher viscosity than water about 78 mPas. It can form several hydrates.
What kind of products can sodium hydroxide be used for?
Sodium hydroxide is generally used as a solid or a diluted in a 50% solution. This chemical is used to manufacture soaps, rayon , paper, explosives, dyestuffs, and petroleum products. It is also used in processing cotton fabric, laundering and bleaching, metal cleaning and processing, oxide coating, electroplating, and electrolytic extracting.
Why is sodium hydroxide used as a caustic agent?
Sodium Hydroxide 10% forms a strongly alkaline and caustic solution. As a caustic agent, it is used to destroy organic tissue by chemical action [L1968]. DrugBank
