Question

Table salt (NaCl) is an ionic compound. As with other ionic compounds, NaCl dissolves in water. When placed in water, Na and Cl form ions. Na has a positive charge and Cl has a negative charge. Describe how water molecules interact with these ions.

Answer 1

On addition to water the Na+ section of NaCl is attracted to the oxygen side of the water molecules, while the Cl- side is attracted to the hydrogens' side of the water molecule. This causes the sodium chloride to split in water, and the NaCl dissolves into separate Na+ and Cl- atoms.

Answer 2

Water Molecules Interaction With Table Salt.

Explanation:

• Salt (NaCl) get dissolved in water because of the electrical charges as well as for the reason that both water and salt are polar compounds, which have positive and negative charges in the molecule on their opposite sides.
• Ionic bonds are present in the table salt as they have two ions that is sodium and chloride.
• An electrical charge gradient is formed between the chloride ion which is negatively charged and the sodium ion which is positively charged.
• Similarly water molecule is polar ionic substance. Instead of this also the bond formed between the two hydrogen atoms which are positively charged and the oxygen which is negatively charged is covalent.
• After addition of salt the counteracting atoms of each substance that is salt and water start interacting which leads to the attraction between the chloride ions (negative) being attracted by the positively charged hydrogen ions and vice versa in the case of sodium and oxygen entity.
• This leads to the shear tension between the sodium and chloride ions and being less stronger ionic bond as compared to covalent bond the sodium and chloride ions are separated and start interaction with the water molecules and forms a homogenous mixture.
