What else can I help you with?
Is sodium polyatomic?
Solid sodium is a metal, there is a lattice of sodium atoms with a "cloud" or sea of electrons delocalised across it.#
Atomic mass of sodium?
The atomic mass of sodium is 22.989768 a.m.u.
What is ratio of sodium and chlorine?
In sodium chloride, the ratio is 1/1.
What is the relative atomic mass of sodium?
Sodium is a meta element. Atomic mass of it is 23.
What is a real life example of polarity of water?
A real-life example of the polarity of water is its ability to dissolve salt (sodium chloride). The positive end of water molecules attracts the negatively charged chloride ions, while the negative end attracts the positively charged sodium ions, effectively pulling them apart and dissolving the salt. This property is crucial for various biological processes, as it allows for the transport of nutrients and waste in living organisms. Additionally, water's polarity contributes to its high surface tension, which enables small insects to walk on its surface.
How do you prepare a 0.4 molar solution of sodium hydroxide from 96 percent sodium hydroxide pellets?
16.5g 97% pure NaOH pellets dissoved in 1 litre of distilled
How do you prepare 1.0L of 0.1M of sodium hydroxide from solid sodium hydroxide pellets?
To prepare 1.0L of 0.1M sodium hydroxide solution, you need to dissolve 4 g of solid sodium hydroxide pellets in water and then dilute the solution to 1.0L. Measure 4 g of sodium hydroxide pellets on a balance, dissolve them in less than 1.0L of water, and then make up the volume to 1.0L with additional water. Be cautious as sodium hydroxide is a caustic compound – wear appropriate safety gear and handle with care.
How is sodium hydroxide available in the laboratory?
Usually in the form of tiny spherical white pellets.
Does concentrated phosphoric acid react with pure sodium hydroxide pellets?
Yes, indeed!
What element turns white when its container was opened?
This element is sodium - a layer of sodium oxide is formed on the surface of the metal.
How many atoms fit into sodium?
it depends on the surface area of the sodium
Is sodium shiny?
The surface of sodium rapidly oxides and forms a grody corrosion layer, but a freshly cut surface of sodium is indeed shiny and will remain that way in an inert atmosphere.
Why does a freshly cut piece of sodium have a shiny surface then after a while it turns white?
When sodium is exposed to air, it reacts with oxygen and moisture to form sodium oxide and sodium hydroxide on its surface. These compounds have a different optical property compared to the shiny metallic sodium, resulting in the white appearance of the surface over time.
Why does the surface of sodium go dull if you cut it?
When the surface of sodium is exposed to air or moisture, it quickly oxidizes, forming a layer of sodium oxide. This oxide layer gives the sodium a dull appearance. To maintain the shiny surface of sodium, it is often stored in oil or inert environments to prevent oxidation.
Why is a freshly cut piece of sodium's surface shiny?
Sodium in its natural state is shiny, like most metals. When sodium interacts with oxygen in the air, it become sodium oxide, which is much more dull. As a result, when you cut into a piece of sodium, you reveal a brand new part of the sodium that has not yet become sodium oxide and is still shiny.
How does sodium carbonate affect the surface tension of water?
sodium carbonate has quite amount of salt in it. And the salt water is inversely proportional to water containing soap.Hence sodium carbonate affect the surface tension of water rather we say sodium carbonate loss the strength of the surface tension of the water.thanks by,(Arjun Babhulkar)
What is the effect of sodium chloride on the surface tension of water?
The surface tension of water is increased for salted water.Sodium chloride increase the surface tension of water.
