What happens if you add water to NaOH?
Solid NaOH consists of Na+ and OH- ions packed into a crystalline lattice.
When this solid is added to water, the ions float apart leading to extra OH- ions in the water: NaOH → OH- + Na+.
The resulting large concentration of OH- makes the solution more basic and leads to a dramatic increase in the pH..
How do you neutralize sodium hydroxide?
To neutralize acids, a weak base is used. Bases have a bitter or astringent taste and a pH greater than 7. Common bases are sodium hydroxide, potassium hydroxide and ammonium hydroxide. Bases are neutralized by using a weak acid.
Does NaOH react with oxygen?
Sodium hydroxide can be used to react with nonmetal oxides like these. A nonmetal oxide is a compound that contains a nonmetal like carbon or sulfur bonded with oxygen. In these reactions, sodium hydroxide will react with the nonmetal oxide to produce an ionic compound and water.
Why does sodium hydroxide heat up in water?
The heat evolved as a result of mixing solid sodium hydroxide with water is due to the the -OH ions incredible stability. Heat is emitted as a result of the chemical species being brought to a lower energy state.
What is the pH of sodium hydroxide in water?

How does sodium hydroxide dissolve in water?
When sodium hydroxide (NaOH) dissolves in water, it separates into positively – charged sodium ions (cations) and negatively – charged hydroxide ions (anions). These ions move around in the water, free and independent of each other, though cations tend to be surrounded more closely by anions and vice versa.
Does sodium hydroxide react with water?
Sodium metal reacts rapidly with water to form a colourless basic solution of sodium hydroxide (NaOH) and hydrogen gas (H2). The reaction continues even when the solution becomes basic. The resulting solution is basic because of the dissolved hydroxide. The reaction is exothermic.
Will NaOH dissolve in water?
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. NaOH is insoluble in ether and other non-polar solvents.
Can you make sodium hydroxide?
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.
How do you dilute sodium hydroxide?
Stir the sodium hydroxide, a little at a time, into a large volume of water and then dilute the solution to make one liter. Add sodium hydroxide to water—do not add water to solid sodium hydroxide.
How do I make a 50% NaOH 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 does sodium hydroxide react with?
Sodium Hydroxide reacts with STRONG ACIDS (such as HYDROCHLORIC, SULFURIC and NITRIC); WATER; and MOISTURE to rapidly release heat. Sodium Hydroxide reacts with METALS (such as ALUMINUM, LEAD, TIN and ZINC) to form flammable and explosive Hydrogen gas.
