what happens when NaCl(s) is dissolved in water?
(1)Cl-ions are attracted to the oxygen atoms of the water
(2)Cl-ions are attracted to the hydrogen atoms of the water.
(3)Na+ions are attracted to the hydrogen atoms of the water.
(4)no attractions are involved; the crystal just falls apart.
the question you helped me w. earlier, so its 2 right ?
right
To determine what happens when NaCl(s) is dissolved in water, we need to consider the nature of NaCl and water molecules.
NaCl is an ionic compound consisting of sodium (Na+) and chloride (Cl-) ions. Water (H2O) is a polar molecule with oxygen (O) having a slight negative charge and hydrogen (H) having a slight positive charge.
When NaCl(s) is dissolved in water, the water molecules surround the Na+ and Cl- ions due to their opposite charges. The process involves the ions getting separated from each other in the solid crystal and getting surrounded by the water molecules.
In the case of NaCl, the chloride (Cl-) ions are attracted to the hydrogen atoms of the water due to the electrostatic forces between the positive hydrogen atoms and the negative chloride ions. So, the correct statement is:
(2) Cl- ions are attracted to the hydrogen atoms of the water.
Therefore, the correct answer is option 2.
