# Forces of attraction of hydrated potassium ion in aqueous solution

I want to study the intermolecular forces (IMFs) in hydrated potassium ion, $\ce{K+ (aq)}$ in an aqueous solution of $\ce{KCl}$. According to my thoughts, among the 4 IMFs I know:

• London dispersion forces (LDFs);
• Dipole-Dipole interaction;
• Hydrogen bonding;
• Ion-dipole forces

LDFs are definitely included, but my question is whether dipole-dipole is included as well (because KCl is a polar substance)?

• KCl is not a molecule at all. – Ivan Neretin Nov 16 '17 at 8:47
• KCl is a formula unit. – andselisk Nov 16 '17 at 8:51
• K+ is a spherical ion. The water molecule has a dipole. So which do you think are relevant? – Ian Bush Aug 10 at 7:32
