The shape and charge distribution in a water molecule cause it to have a permanent dipole moment, which consist of a positive electric charge and a negative charge separated by a distance in space. Therefore, the part of a water molecule that corresponds to the negative charge of its dipole moment is attracted to positive ions, and the part of a water molecule that corresponds to the positive charge of its dipole moment is attracted to negative ions.

In the case of dissolving an ionic compound, the positive ion (cation) attracts the partially negative oxygen atom of the water molecule due to its charge, forming a hydrogen bond. Similarly, the negative ion (anion) attracts the partially positive hydrogen atoms of the water molecule, also forming a hydrogen bond. This attraction between water molecules and ions helps to break apart the ionic lattice structure and allows the compound to dissolve in water.

When NaCl is dissolved in water negative end of the water molecules is attracted towards what?
Ion-dipole attraction dictates that the negative pole of a water molecule will be attracted to the sodium cation and the positive pole of a water molecule will be attracted to the chloride anion.
Why does drops of ethanol are attracted to a charged strip?
Drops of ethanol are attracted to a charged strip because ethanol is a polar molecule with a slightly positive and negative end. When a charged strip is brought near the drops, the positive or negative end of the ethanol molecule is attracted to the opposite charge on the strip, leading to the movement of the drops towards the strip.
What happens when ionic bonds are put in water?
When ionic bonds are put in water, the ions in the compound dissociate due to the polar nature of water molecules. The positive ions are attracted to the oxygen atoms of water, while the negative ions are attracted to the hydrogen atoms. This results in the formation of hydrated ions and the compound dissolving in water.
In an aqueous solution of an ionic salt the oxygen atom of the water molecule is attracted to?
the partially negative charge on the oxygen atom of the salt's anion. This attraction forms hydrogen bonds between the water molecule and the anion.
When NaCl dissolves in water which end of the water molecule is attracted to the Na plus?
The oxygen end of the water molecule is attracted to the Na+ ion. This attraction occurs due to the partial negative charge on the oxygen atom of the water molecule and the positive charge on the sodium ion.
What parts of the calcium chloride are attracted to what parts of the water molecule?
The positive calcium ions in calcium chloride are attracted to the negative oxygen atom in the water molecule, while the negative chloride ions are attracted to the positive hydrogen atoms in the water molecule.
When NaCl is dissolved in water negative end of the water molecules is attracted towards what?
Ion-dipole attraction dictates that the negative pole of a water molecule will be attracted to the sodium cation and the positive pole of a water molecule will be attracted to the chloride anion.
When an ionic molecule dissolves in water what does the water molecule do?
Surrounds the ions with the hydrogen, positive end, attracted to the negative ion ( Cl -, for instance ) and the oxygen, negative end, attracted to the positive ion ( Na +, for instance ).
What characteristic of water helps it cause a mineral to dissolve?
Water is a polar molecule meaning the oxygen part is negative the hydrogen is positive, so in an ionic compound the negative ion get attracted to the hydrogen and the positive ion to the oxygen.
What kind of molecule has two positive atoms attached to a positive atom?
There is no such thing. A positive molecule will only be attracted to a negative molecule.
Why does drops of ethanol are attracted to a charged strip?
Drops of ethanol are attracted to a charged strip because ethanol is a polar molecule with a slightly positive and negative end. When a charged strip is brought near the drops, the positive or negative end of the ethanol molecule is attracted to the opposite charge on the strip, leading to the movement of the drops towards the strip.
What happens when ionic bonds are put in water?
When ionic bonds are put in water, the ions in the compound dissociate due to the polar nature of water molecules. The positive ions are attracted to the oxygen atoms of water, while the negative ions are attracted to the hydrogen atoms. This results in the formation of hydrated ions and the compound dissolving in water.
Why are ironic substances soluble in water a polar solvent?
Ironic substances are often soluble in water because the polarity of water molecules allows them to interact with and surround the ions or charged particles present in the ironic substance, facilitating dissolution. The positive end of water molecules (hydrogen side) interacts with negative ions, while the negative end (oxygen side) interacts with positive ions, enabling the substance to dissolve in water.
Water dissolves many ionic and molecular compounds because of its what?
Water dissolves many compounds because of its polarity. The water molecule has a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom, allowing it to interact with both positively and negatively charged ions in the solute molecules, facilitating their disassociation and dissolution in water.
When placed between oppositely charged metal plates the region of a water molecule that is attracted to the negative plate is the .?
partially positively charged hydrogen end of the molecule.
In an aqueous solution of an ionic salt the oxygen atom of the water molecule is attracted to?
the partially negative charge on the oxygen atom of the salt's anion. This attraction forms hydrogen bonds between the water molecule and the anion.
When NaCl dissolves in water which end of the water molecule is attracted to the Na plus?
The oxygen end of the water molecule is attracted to the Na+ ion. This attraction occurs due to the partial negative charge on the oxygen atom of the water molecule and the positive charge on the sodium ion.
