Explain how a water molecule can be attracted to both a positive ion and a negative ion when dissolving an ionic compound?
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.

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.
What does it mean to be a polar compound?
A polar compound is a molecule in which there is an uneven distribution of electron density, resulting in a partial positive and partial negative charge within the molecule. This charge separation leads to the molecule having a positive and negative end, making it interact with other polar molecules or ions, such as 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.
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 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.

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.
Water dissolves many ionic and molecular compounds because of its what?
Water is a highly polar molecule which means that one side of the molecule is slightly positive and the other is slightly negative. This means that water molecules are attracted and can form weak bonds with molecules that also have positive sides and negative sides (polar molecules). Basically, the positive side of the water molecule is attracted to the negative side of the polar molecule and the negative side of the water molecule is attracted to the positive side of the polar molecule. Is this way the water is able to surround and separate the polar molecules. The story is much the same for an ionic compound which contains a mixture of positive and negative ions. The positive side of the water molecules surround the negative ions and the negative side of the water molecules surround the positive ions.
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.
Which end of the water molecule is attracted to the sodium ion?
Since water is a slightly polar molecule (the hydrogen end being slightly positive and the oxygen ends being slightly negative) the positively charged sodium ion (Na+) will be attracted to the oxygen end of the water molecule.
