Chemical Properties of Sodium Oxide – Na 2 O. Account for the fact that graphite conducts electricity and diamond does not. Hence, wouldn't sodium from a stronger bond with oxygen, as compared to aluminium? Sophia. Thus their bond cannot be broken easily. Answer Save. nitrogen dioxide Sodium oxide is a chemical compound with the formula Na 2 O.It is used in ceramics and glasses.The compound is the base anhydride of sodium hydroxide; when water is added to sodium oxide, NaOH is produced.. Na 2 O + H 2 O → 2 NaOH. In terms of it's bonding and structure . Why is the melting point of aluminium oxide higher than that of sodium oxide? Magnesium oxide is an ionic compound ( because it consists of a metal and a non-metal)In ionic compounds, electrons from the outer shell exchange between the at… 4 Answers. Does Is Mean Higher Chances Of Melting Or What? Ionic or electrostatic compounds have very strong electrostatic forces of attraction. These ions … 0 0. lenahan. Sodium oxide has a formula of Na2O. The second answer is incorrect. If it sublimes, you won't get any liquid to electrolyse! This explains why sodium oxide has a higher melting point than sulfur trioxide. The melting point of a material is primarily related to bond strength. Awesomeness. How does a catalyst effect the rate of reaction? 1 decade ago. So Al2O3 has a higher melting point.... Why N2H4 Has High Boiling Point Than C2H4? What are the oxidation numbers of each element in these examples: a) H2SO4 b) N2 c) NH4+. However, other factors--such as crystal structure, atomic weight, and electron structure--can also influence the melting point. Sodium will lose an electron to form a cation and oxygen will gain 2 electrons to form anion. Relevance. You can change your choices at any time by visiting Your Privacy Controls. Which Would Have A Higher Melting Point, Sodium Chloride Or Aluminum Oxide? ..... it is a lattice of ions held together by many strong ionic bonds Predict an equation for the reaction of a period 2 oxide with water e.g. Why dose sodium oxide have a high melting point? Source(s): Chemistry student, this is explanation has been simplified, do ask me for a detailed one if you need it. Favorite Answer.

This is why sodium oxide has a high melting point. Source(s): Chemistry student, this is explanation has been simplified, do ask me for a detailed one if you need it. This explains why sodium oxide has a higher melting point than sulfur trioxide. Why does sodium oxide have a high melting point ? The first answer is correct. The first answer is correct. We and our partners will store and/or access information on your device through the use of cookies and similar technologies, to display personalised ads and content, for ad and content measurement, audience insights and product development. Compare the structures of Diamond and Graphite, making references to the bonding, the shape of the structures, and location of the electrons within the structures. Because there exists hydrogen bond between N2H4.... What Does High Melting Point Mean? Why does sodium carbonate have a high melting point? Why does sodium oxide have a high melting point ? Since sodium is a metal and oxygen is a non metal, sodium oxide is an ionic species. Sodium will lose an electron to form a cation and oxygen will gain 2 electrons to form anion. Sophia. 0 0. lenahan. I know that aluminium ion has a charge of +3, and sodium has a charge of +1. In terms of it's bonding and structure . Have a Free Meeting with one of our hand picked tutors from the UK’s top universities. Chemistry. Sodium oxide reacts with carbon dioxide to form sodium carbonate.The chemical equation is given below. Sodium is less electronegative than aluminium. Materials with strong bonds between atoms will have a high melting temperature. 2Na 2 O + 3CO 2 → 2Na 2 CO 3. Explain the trends in ionisation energies across the 2nd period of the periodic table. These ions will be arranged in an ionic lattice structure. Thus their bond cannot be broken easily. Because it is a solid ionic compound exists as the crystal lattice, such compounds have high melting points but are easily soluble in water. 4 Answers. 1 0. Ionic or electrostatic compounds have very strong electrostatic forces of attraction. 1 0. Favourite answer. Since sodium is a metal and oxygen is a non metal, sodium oxide is an ionic species. Answer Save. The alkali metal oxides M 2 O (M = Li, Na, K, Rb) crystallise in the antifluorite structure. One to one online tution can be a great way to brush up on your Chemistry knowledge. Al2O3:2030℃. Ionic and metalic bonds are weaker than covalent bonds. Tungsten, rhenium, osmium, tantalum, and molybdenum are among the highest melting point metals. Whether you can electrolyse molten sodium oxide depends, of course, on whether it actually melts instead of subliming or decomposing under ordinary circumstances. Chemistry. Awesomeness. Sodium oxide reacts with some acids (such as hydrochloric acid) to form sodium chloride and water. 10 years ago. Magnesium and aluminium oxides have melting points far too high to be able to electrolyse them in a simple lab. Sodium oxide is an ionic compound and ionic compounds typically have extremely high melting points. Sodium oxide has a formula of Na 2 O. Relevance. There is a strong attractive force between these oppositely charged ions, which require a lot of energy to break lots of these bonds to melt the lattice structure.
