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 part of DNA gives the molecule a negative charge?
The phosphate groups in the DNA molecule give it a negative charge.
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.
What molecule has a positive end and negative end?
A zwitterion, if you mean formal charges. If you just mean relatively positive and negative, then a polar 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.
What part of the H2O molecule is the negative pole?
there is no negative pole in h2o molecule

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.
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.
Is a molecule part of a atom?
NO!!!! It's the other way around. An atom can be part of a molecule. e.g. Water (H2O) . It has three atoms, making a molecule of water. So the three atoms are part of a molecule.
What molecule has a positive end and negative end?
A zwitterion, if you mean formal charges. If you just mean relatively positive and negative, then a polar molecule.
Is water a negatively or positively charged molecule?
Water is a neutral molecule, meaning it does not have a positive or negative charge overall.
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.
What kind off molecule has a positive end and a negative end?
A polar molecule such as water
A molecule that has a negative and poositve end is?
A polar molecule is one that has a negative and positive end due to an uneven distribution of electron density. Water is a common example of a polar molecule, with its oxygen atom being partially negative and its hydrogen atoms being partially positive.
