What happens to ionic and covalent compounds when they are dissolved in water?

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.

∙ 11y agoThe 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.

∙ 13y agoWhen 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.)

∙ 11y ago-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

∙ 11y agoThe bonds between the atoms dont break when covalent compounds are dissolved. However there are not many covalent compounds that generally dissolve in water.
Wiki User
∙ 12y agoThe cations and anions from the ionic compound separate to greater average distances from one another than prevailed in the compound before it was dissolved.

In Which state do ionic compounds and covalent compounds conduct electricity?
Ionic compounds conduct electricity in molten state (melted) or when dissolved in a solution. Covalent compounds do not conduct electricity. Period.
Is telephone receiver a ionic or covalent compound?
covalent compounds --------- It is inadequate to discuss about a telephone in terms of ionic and covalent compounds.
Are you made of ionic or covalent compounds?
Living things are made up of both ionic and covalent compounds.
Is Vaseline ionic or covalent?
Petrol is a mixture of organic compounds. These organic compounds have covalent bonds.
Why do covalent compounds have lower melting points then ionic compounds?
Covalent compounds tend to be negatively charged than an ionic compound.

Are you made of ionic or covalent compounds?

What releases ions when dissolved in water?
Soluble ionic compounds like NaCl, and some covalent compounds like HCl(g) which will dissociate in water.
Is Vaseline ionic or covalent?
Petrol is a mixture of organic compounds. These organic compounds have covalent bonds.
Why do covalent compounds have lower melting points then ionic compounds?
Covalent compounds tend to be negatively charged than an ionic compound.
Is a telephone receiver an ionic compound a ionic compound or a covalent 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.
What is the difference between and ionic and covalent bond?
Compounds with covalent bonds form molecules. Compounds with ionic bonds form ionic lattices.
Do ionic compounds have lower boiling points than polar covalent?
Ionic compounds have higher boiling points than covalent compounds.
Write down the differences between ionic compound from 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.
Are melting points of covalent compounds high or low compared to ionic compounds?
Ionic compounds have strong electrostatic force of attraction and hence have higher melting points than covalent compounds.
How do you know if you have an ionic or molecular compound?
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.
