What Is The Density Of Sodium Hydroxide? 

The density of sodium hydroxide will tell you much about it. Because it is one of the main properties of the compound. Sodium hydroxide’s chemical formula or scientific symbol is NaOH, in which Sodium’s symbol is Na, O is the oxygen, and H is the hydrogen element. Sodium hydroxide also called ‘Caustic Soda’ or lye is a corrosive white crystalline solid that contains the Na+ cation and the OH anion. It readily absorbs moisture until it dissolves. While talking about sodium hydroxide uses, it is the most widely used industrial alkali and is often used in drain and oven cleaners. Without extending the introductions let’s move to the density of sodium hydroxide. 

What Is The Density Of Sodium Hydroxide? 

The density of sodium hydroxide is 2.13 g/cm3, and the melt has a density of 2.77 g/cm3 at 350 deg C. The solution of the sodium hydroxide appears to be a colorless liquid. It has more density than water. Therefore, when you mix sodium hydroxide into the water, then you will find that sodium hydroxide will sink into the water. When you observe the density graph of sodium hydroxide due to temperature, then you will find that the solubilization curve tends to shift to lower NaoH concentration with the increases in temperature. This implies that the rise in the temperature is able to reduce the consumption of sodium hydroxide in order to achieve similar solubilization. 

Here are the different densities of sodium hydroxide, 

  • The density of sodium hydroxide in g/ml is 1.2185 g/mL 
  • The density of sodium hydroxide in kg/m3 is 2100 kg/m3 
  • The density of sodium hydroxide liquid is 2.13 g/cm3 
  • The density of aqueous sodium hydroxide is 2.13 g/cm3 
  • The density of 50 sodium hydroxide is 1.52 g/cm3
  • The density of sodium hydroxide solutions is 2.13 g/cm3 
  • The vapor density of sodium hydroxide is 1.515 g/mL 

Now, you know the density of sodium hydroxide g/ml. Let’s know the definition of NaOH density in detail. . 

Definition Of Density Of Sodium Hydroxide 

The density of NaoH is defined as the amount of NaoH compound occupied in one cubic centimeter of space. In another language, the ratio of mass and volume of the NaoH is called the NaOH density. Sodium hydroxide common name is caustic soda, soda, or lye. The definition of the density of NaOH can be written in the equation form, 

The density of Sodium Hydroxide = mass of Sodium Hydroxidevolume of Sodium Hydroxide g/cm3 

In the symbolic form, 

                 D =    mv g/cm3 

Where, d – the Sodium Hydroxide density, 

              v – the volume of Sodium Hydroxide, and 

             m – the mass of Sodium Hydroxide 

Now, learn how to measure the density of sodium hydroxide. 

How To Calculate Density Of Sodium Hydroxide? 

To measure the density of sodium hydroxide you need to calculate its mass and volume first. And to calculate the mass of NaOH you need to know the chemical properties of the elements from the periodic table. Well, the molecular mass of sodium hydroxide is 40. Similarly, the volume of the Sodium hydroxide is 19.0 mL. These all parameters of all elements in the periodic table are already measured. So, you don’t need to measure it separately. Let’s understand it by taking an example. 

If the molarity of the Sodium Hydroxide compound is 2 then what will be the density of the 3 molal solutions of NaOH? 

Well, 3 molal solution of NaOH means 3 moles of NaOH dissolved in 1 kg solvent. So the mass of the solution will be 1000 g solvent + 120 g of NaOH = 1120 g solution 

Molar mass of NaOH is = 23+16+1 = 40 grams and 3 moles of NaOH 

                                                          =40 x 3 

                                                          = 120 g 

So, the volume of the solution is =(Moles of solute x 1000)/Molarity 

                                                      =(3 x 1000)/3

                                                      = 1009 mL 

Now, the density of NaOH is = 1120/1009  

                                                = 1.110 g/mL

What Is Sodium Hydroxide Used For?

Manufacturers may use sodium hydroxide to produce soaps, rayon, paper, products that explode, dyes, and petroleum products. Other tasks that may use sodium hydroxide include processing cotton fabric, metal cleaning and processing, oxide coating, electroplating, and electrolytic extraction.

Is Sodium Hydroxide Okay For Skin?

Just to be absolutely clear: It’s not safe to apply pure sodium hydroxide to your skin, in any amount or concentration. Sodium hydroxide can cause chemical burns and severe skin damage.

Why Is Sodium Hydroxide Toxic?

Sodium hydroxide is corrosive to all body tissues; concentrated vapors cause serious damage to the eyes and respiratory system. Ingestion of sodium hydroxide, which occurs frequently in children, can cause severe necrosis, with stricture of the esophagus and death.

Is Sodium Hydroxide Same As Baking Soda?

Complete step-by-step answer:- Sodium hydroxide is not known as baking soda. Baking soda is another name for sodium bicarbonate. – Sodium hydroxide comes from carbonate sodium, formerly known as ‘caustic soda’.

What Is The Density Of HCl And NaOH?

Minimum Temperature as Initial Temperature=43.5°C. Density of HCl & NaOH Soultion=1.04 g/mL. Specific Heat of HCl & NaOH Solution=4.017 J/g°C.


Sodium hydroxide, Caustic soda, or NaOH is a white crystalline odorless solid that absorbs moisture from the air. It is a manufactured substance. When NaOH is dissolved in water or neutralized with acid it liberates substantial heat, which may be sufficient to ignite combustible materials. NaOH is very corrosive and generally used as a solid or a 50% solution. It 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. This was all about the density of sodium hydroxide.
