Hydrogen containing covalent bonds interact with water strongly enough that their molecules dissociate into ions. In aqueous solutions, they are called acids. Examples are Hydrochloric acid (HCl), Nitric acid (HNO3), and Sulfuric acid (H2SO4).

Is silicon dioxide soluble in non polar benzene?
No, silicon dioxide forms a network covalent structure, and so doesn't dissolve in anything:
Is water an ionic compound that can dissolve only ions?
No. Water is a largely covalent compound that spontaneously ionizes only to give concentrations of 10-7 molar for each of hydrogen and hydroxide ions. However water also has a high dielectric constant and for that reason can dissolve many ionic compounds. Water can also dissolve sufficiently polar organic compounds, such as sugar, with little or no trace of ionic character.
Why do ionic compounds do not dissolve in organic solvent?
The typical rule for dissolving substances in one another is that substances most readily dissolve other substances with similar bonds. Alkanes are nonpolar because they have mostly nonpolar bonds. On the other hand, ionic compounds have ionic bonds, which are extremely polar. Therefore, because the difference in bond type, ionic compounds do not dissolve in any alkane.
Why can water dissolve so many compounds?
Water, (h2o) is a polar compound, wherein it has a magnetic charge. This charge attracts an opposite charge such as salt and decouples the sodium chloride ion.
The process by which some molecular compounds dissolve in water to form ions is?
Ionization
Some covalent compound dissociate dissociate into ions when they dissolve in water and what atom do these compounds have in their structure?
oxygen
Are substances with ionic or covalent bonds more likely to dissociate in water?
Ionic compounds dissociate when they dissolve in water.
Are ionic compounds more likely to dissolve in water than covalent compounds?
Often - yes. the reason they break apart is the hydration energy of the ions- many ionic compounds are soluble in water and dissociate into ions, however there are ionic solids such as CaCO3 which are not soluble. The bonds in covalent compunds are often not broken- for example thise in alkanes. However there are covalent compounds which do react with water and dissolve.
What is the difference in the way ionic and covalent compounds dissolve in solutions?
ionic compounds split into individual ions were as covalent compounds dissolves and is surrounded by water molecules
Does covalent or ionic substances dissolve in water faster?
Ionic compounds
How can water dissolve some ionic compounds as well as some molecular compounds?
Water can dissolve some ionic compounds as well as some molecular compounds because of its polarity. It is polar enough to dissolve ionic compounds into their ions. Water does not dissolve molecular compounds by breaking covalent bonds, but through intermolecular forces.
When you dissolve something is it a chemical change?
With ionic compounds anyway, they dissociate into their ions. The chemical change is an equilibrium until separated.
Can covalent compounds dissolve in water?
You can NOT dissolve 'covalent BONDS' because a bond is one couple of two electrons which hold their two 'parent' atoms together in one molecule.Try asking the question again with what you want to know, not what you have only 'heard of'.
Salts that dissolve in water and dissociate into charged particles called ions?
They are soluble substances, which would include polar substances and ionic compounds.
Why do covalent compounds dissolve in ethanol not in water?
The polar covalent compounds are easily soluble in water as HCl, HNO3, H2SO4, Glucose and most of the sugars, Sugar has many polar covalent bonds, in the C-O-H groups, and the molecules of sugar fit easily into the hydrogen bonded microstructure of liquid water.
Why ozone will not dissolve in water?
Ozone is a non-polar covalent molecule. As water dissolves only polar compounds.
Why don't some covalent compounds dissolve in water?
because some of those bonds are polar and from associations with the water.
