So how strong is the bond connecting the H ion and the atom in the compound? Well, suppose you're holding somebody's hand and you're holding their hand tightly with a good grip. Well, then the other person will not be able to let go of their hand that easily. However, if your grip is weak and you're not holding it tightly, then that person will be able to let go of their hand the same way that weak bonds will release the H plus ion with greater ease. So whenever you have a base that comes around, that base will be able to take away that H plus ion if the bond is weak. So weaker bonds equals better acids.
