We’re going to use the theory “likes” dissolving “likes” which states that the solvent can only completely dissolve the solute if they share similar polarity or have strong intermolecular force
NaBr → ionic compound → made up of ions
H2O → polar covalent compound
Intermolecular Forces (IMF) are the attractive forces between 2 molecules.
• Ion-dipole: strongest IMF → attraction between an ion and a polar compound.
Why does NaBr dissolve in water?
a) because of strong dispersion forces between NaBr and water.
b) because of strong ion-dipole forces.
c) because of strong dipole-dipole interactions between NaBr and water.
d) because of strong hydrogen-bonding interactions between NaBr and water.
