Water is a very good solvent. When an ionic compound is dissolved in water, it breaks into its contituent radical ions. say for example if you dissolve NaCl in water, then it decomposes into Na+ & Cl-
another example, when (Na)2SO4 is dissolevd in water it dissolves into two Na+ ion and one SO4- ion.
The bonds of ionic compounds tend to dissociate into their positive and negative ions as their molecules are hydrolyzed by the water.
The bonds of covalent compounds remain intact even in those that dissolve readily in water, such as sugar alcohol and others.
Ionic compounds dissolve in water. Because of the intermolecular forces in water, it is able to pull the molecule apart. For example, when table salt is added to water (NaCl) it is broken down into Na and Cl.
When an ionic compound is dissolved in water, it is broken up into its positive and its negative ions. We shall use Table Salt for our example. It has the formula NaCl, which stands for Sodium Chloride. It becomes a Sodium ion and a Chlorine ion. Water has the formula H2O. That is two atoms of Hydrogen and one of Oxygen. The Hydrogen atoms are on one side.
The Chlorine ion becomes surrounded by Hydrogen atoms and the Sodium atom becomes surrounded by Oxygen atoms.
Covalent compounds consisting of long chains of carbon atoms do not dissolve in water. They do not have anything to attract either the Oxygen atoms or the Hydrogen atoms.
By putting an acid or alcohol group on the end of a covalent compound, it will make the compound dissolve in water. Part of the compound will be attracted to the Oxygen atoms in the water and the other part to the Hydrogen atoms. (When the chains get 17 atoms long and longer something else happens, but we will not get into that.)
-they are broken up into their respective ions... for example: when table salt (NaCl) is disolved, it is broken up into Na+ and Cl-
-they are pulled apart by water molecules
The bonds between the atoms dont break when covalent compounds are dissolved. However there are not many covalent compounds that generally dissolve in water.
The cations and anions from the ionic compound separate to greater average distances from one another than prevailed in the compound before it was dissolved.
They dissolve
it ionizes
Ionic compounds conduct electricity in molten state (melted) or when dissolved in a solution. Covalent compounds do not conduct electricity. Period.
covalent compounds --------- It is inadequate to discuss about a telephone in terms of ionic and covalent compounds.
Living things are made up of both ionic and covalent compounds.
Petrol is a mixture of organic compounds. These organic compounds have covalent bonds.
Covalent compounds tend to be negatively charged than an ionic compound.

Living things are made up of both ionic and covalent compounds.
Soluble ionic compounds like NaCl, and some covalent compounds like HCl(g) which will dissociate in water.

Covalent compounds tend to be negatively charged than an ionic compound.
im guessing covalent compound It is inadequate to discuss about a telephone in terms of ionic and covalent compounds. But, plastics are covalent compounds.
Compounds with covalent bonds form molecules. Compounds with ionic bonds form ionic lattices.
Ionic compounds have higher boiling points than covalent compounds.
Ionic Compounds are formed by complete transfer of electrons while Covalent compounds are formed by sharing of electrons. Ionic compounds have higher melting points while covalent compounds have lower.
Ionic compounds have strong electrostatic force of attraction and hence have higher melting points than covalent compounds.
The easiest difference to see is that ionic compounds dissolved in water conduct electricity, while covalent ones do not. Ionic compounds consist of a metal and non-metal, but covalents have only non-metal atoms.
