When sodium chloride is dissolved into water what part of the water molecule does sodium get attracted to?
The negative dipole of the oxygen
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.
What explains the solubility of ionic substances in water?
Ionic substances dissolve in water because of the attraction exerted between positive ions and the negatively charged oxygen part of the water molecule, and also between negative ions and the positively charged hydrogen part of the water molecule.
Why does water dissolve substances?
Water is a universal solvent because substances get dissolve in water easily. It is due to the polarity of each water molecule. The hydrogen has a positive charge, thus attracting the negative part of an ionic compound, while the oxygen has a negative charge and thus attracts the positive part of an ionic compound.
Why does each molecule of water acts as a tiny magnet?
Water molecules are polar, which means that one part of the molecule has a positive charge and the other has a negative charge just like the polar ends of a magnet.
When sodium chloride is dissolved into water what part of the water molecule does sodium get attracted to?
The negative dipole of the oxygen
What part of the H2O molecule is the negative pole?
there is no negative pole in h2o molecule

What struggle produces the partial negative and partial positive charges on a water molecule?
The water molecule has a partial negative and partial positive charge because it is a polar molecule. Electrostatic attraction between the partial negative and partial positive molecules gives the water molecule its partial charge.
Why is a water molecule considered to be a polar molecule?
A water molecule is considered a polar molecule because of its shape. That is, its poles contain opposing charges, the positive and negative charge.
Why does each molecule of water acts as a tiny magnet?
Water molecules are polar, which means that one part of the molecule has a positive charge and the other has a negative charge just like the polar ends of a magnet.
Does dissociation of salts keep salt molecules stable in water?
When sodium chloride is dissolved in water, a process called solvation occurs. Water is a polar in nature and it is a polar solvent. The water molecule has a positive end and a negative end . The positive part of the water molecule is attracted to the negative part of the sodium chloride, the chloride ion. The negative part of the water is attracted to the positive part of the sodium chloride, the sodium ion. Thus, the sodium chloride dissociates, or breaks apart 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 are ironic substances soluble in water a polar solvent?
Water molecules are polar in character, they possess a dipole. The positive part of the water molecule is attracted to the negative ion in the ionic substance, and the negative part of the water molecule to the positive ion. The resulting release of energy encourages the process of dissolving. The solubility of ionic substances is variable and depends on other properties of the constituent elements.
What causes water to be more polar molecule?
Because of the way the hydrogens bond to the oxygen in water, the molecular geometry is a bent or angular shape, and the oxygen has 2 lone pairs of electrons. This makes the oxygen part of the water molecule rather negative relative to the hydrogen part of the molecule, which is rather positive. Thus, there is a separation of charge, and this is what makes the water molecule so polar.
