NaOH is a white crystalline solid that is deliquescent, which means that it absorbs moisture from the air. It is also a strong base that can hurt you if you touch it or ingest it. Handling Sodium Hydroxide makes your fingers feel slippery because it is turning the fat in you fingertips into soap. Don't handle it.
What else can I help you with?
Why do we standardize the NaOH solution that we made by dissolving a measured mass of solid NaOH?
Standardizing the NaOH solution by dissolving a measured mass of solid NaOH ensures that the concentration of the solution is accurately known and consistent for use in experiments or analyses.
How do you prepare 1L of 0.1M NaOH from solid NaOH?
Dissolve 4g of solid NaOH in water and then dilute to the 1L final volume to make a 0.1M solution. Be sure to wear appropriate protective gear and handle NaOH with care, as it is a caustic substance.
What amount of solid Naoh must be added to 750g of an aqueous solution to make 2.5 percent naoh solution by mass?
You would need to add 18.75g of solid NaOH to the 750g of aqueous solution to obtain a 2.5% NaOH solution by mass.
Does a solid form when NaCl and NaOH are combined in solution?
No, a solid does not form when NaCl and NaOH are combined in solution. NaCl dissociates into Na+ and Cl- ions in solution, while NaOH dissociates into Na+ and OH- ions. The ions remain dissolved in the solution and do not form a solid precipitate.
What state of matter of NaOH?
Sodium hydroxide (NaOH) is a solid at room temperature and pressure. When dissolved in water, it forms a strongly alkaline solution.

Standardizing the NaOH solution by dissolving a measured mass of solid NaOH ensures that the concentration of the solution is accurately known and consistent for use in experiments or analyses.
What is the difference between NaOH s and NaOH aq?
NaOH (s) refers to solid sodium hydroxide, which is in a solid state. NaOH (aq) refers to sodium hydroxide dissolved in water, resulting in an aqueous solution. The (s) and (aq) notations distinguish between the physical states of the substance.

What is the chemical name of solid caustic soda?
Sodium hydroxide (NaOH).
What amount of solid naoh must be added to 750 g of an aqueous solution to make 2.5 percent NAOH solution by mass?
75gm
When Hydrochloric acid reacts with solid NaOH what is the chemical reaction?
The chemical reaction between hydrochloric acid (HCl) and solid sodium hydroxide (NaOH) produces water (H2O) and sodium chloride (NaCl) salt. The balanced chemical equation for this reaction is: HCl + NaOH → H2O + NaCl.
Why should procedures involving solid NaOH be completed quickly?
Procedures involving solid NaOH should be completed quickly to minimize its exposure to moisture in the air. NaOH is hygroscopic, meaning it readily absorbs water from the atmosphere, leading to the formation of a caustic solution. This can make handling the substance more hazardous and less effective for the intended purpose.
What is the specific gravity of NaOH?
The density of pure sodium hydroxide (solid) is 2,13 g/cm3.
Is sodium hydroxide a solid or liquid?
Sodium hydroxide is a solid at room temperature. It is a white crystalline solid that is typically supplied in the form of pellets, flakes, or granules. When dissolved in water, sodium hydroxide forms a caustic solution commonly known as lye.
