Hey I need some help here
When we mix salt into water, often we dont see an increase in
volume.
Is it the H2O molecule thats going into the crystal structure of
the NaCl structure and pushes the Na and Cl apart while the bond
between Na and Cl is not broken
or
is it NaCl disociates into Na+ and Cl- and then goes in between the
gaps between H2O molecules?
HELP!!!!!!!!
