What oxide is soluble in water and is acidic?
An acidic solution can be formed when a non-metal oxide is dissolved in water. For example, magnesium oxide dissolves to form alkaline solutions. Sulfur dioxide and nitrogen dioxide however, will dissolve to form acidic solutions.
Which element of oxide is soluble in water?
Carbon (Group 14) is one answer so long as it is the oxide (CO2), rather than the element itself, which dissolves in water to give an acidic solution. Group-14 element CARBON and Group-15 element NITROGEN forms acidic oxides, both GASEOUS and soluble in water. Not all oxides of Carbon and Nitrogen are acidic.
What may be the group of an element of whose oxide is a gas and dissolves in water to give an acidic solution?
Answer: Oxides of 2A (beryllium) group are basic in nature and thus their aqueous solutions are basic. Oxides of 4A(carbon) group are acidic in nature and their aqueous solution are thus acidic.
What elements form acidic oxides?
Less electronegative elements tend to form basic oxides such as sodium oxide and magnesium oxide, where as more electronegative elements tend to produce acidic oxides as seen with carbon dioxide and phosphorus pentoxide. Some oxides like aluminium oxides are amphoteric.
Is Cuo soluble in water?
Copper(II) oxide
| Names | |

| Magnetic susceptibility (χ) | +238.9·10−6 cm3/mol |
Is sodium oxide soluble in water?
Is sodium oxide soluble in water? No, sodium oxide is not soluble in water. Na2O reacts violently when exposed to water, forming sodium hydroxide in the process. Therefore, sodium oxide must be kept away from water and stored in a dry environment.
What oxides are soluble?
Oxides (O2-) are usually insoluble. Exceptions include Na2O, K2O, SrO, and BaO, which are soluble, and CaO, which is slightly soluble. 3. Hydroxides (OH-) are usually insoluble.
What is an oxide of an element?
oxide, any of a large and important class of chemical compounds in which oxygen is combined with another element. With the exception of the lighter inert gases (helium [He], neon [Ne], argon [Ar], and krypton [Kr]), oxygen (O) forms at least one binary oxide with each of the elements.
What elements form gaseous oxides?
Metal and non-metal oxides
| Element | Type | Oxide |
|---|---|---|
| Magnesium | Metal | Magnesium oxide, MgO – solid white powder |
| Carbon | Non-metal | Carbon dioxide, CO 2 – colourless gas with no odour |
| Sulfur | Non-metal | Sulfur dioxide, SO 2 – colourless gas with choking smell |
Which oxide is most acidic?
Therefore Cl2O7 is the most acidic oxide.
Why is CO2 acidic oxide?
YOU MUST TAKE THE EXAMPLE OF HYDROGEN WHICH FORMS OXIDE H2O WHICH IS NEUTRAL IN NATURE. Co2+h2o gives H2CO3. Thus co2 accepted two pair of electron so it is a acid.
Why is CuO insoluble?
CuO also behaves in this way. Nope, copper can not react with water. I am giving you a fact —- Iron, the element above hydrogen reacts with great difficulty with steam in a very heated state, to form Fe3O4. Even in this reaction, the equilibrium is such that, the reaction is reversible.
Which group does the oxide of an element belong to?
The oxide of an element is gas, is soluble in water, and forms an acidic solution. Which group does the element belong to? Group-14 element CARBON and Group-15 element NITROGEN forms acidic oxides, both GASEOUS and soluble in water. Not all oxides of Carbon and Nitrogen are acidic. Carbon forms two oxides mainly.
Which oxides are soluble in water?
Acidic oxides are typically oxides of non-metallic elements, and they react with base. Oxides, in general, are not “soluble” in water in the sense that they would form a homogeneous mixture or solution. Rather, they may react react with water. Which metal hydroxides are soluble?
Which elements are soluble in hydroxides?
As you can probably see from the periodic table, these elements are Li, Na, K, Rb, Cs, Ca, Sr, Ba. Of course, the hydroxides of these metals are soluble. However, bear in mind that Be (OH)2 and Mg (OH)2 barely dissolve in water.
What elements are formed when metal oxide reacts with water?
Metal Oxides that are formed from elements in group IA and IIA, except for Be and Mg, react with water to create Hydroxides. As you can probably see from the periodic table, these elements are Li, Na, K, Rb, Cs, Ca, Sr, Ba.
