How do bases work?
By wanting to take a proton
By now you must have learned about acids. Acids work by wanting to give a proton. It's strength is determined by how easily the substance gives that proton away. We see HCL. Chlorine is EXTREAMLY electronegative so it takes the hydrogens electron to fill its orbital.
Bases work just the opposite. They are weak or strong based upon how easily they can take a proton. This is where we see NaOH, Sodium Hydroxide. Sodium is not very electronegative but oxygen is also EXTREAMLY electronegative.
This is where we get a reaction between HCL and NaOH. When dissolved they both dissolve completely.
So in two solutions there is
