Final answer:
Bond strength and binary acidity are inversely related; a stronger bond makes a substance less acidic because it's less likely to form H+ ions, while a weaker bond is easier to break and correlates with higher acidity.
Step-by-step explanation:
Bond strength and binary acidity are related in a specific way. Generally speaking, the stronger the bond between a hydrogen atom and another atom or group (A⁻H or B⁻H⁺), the less likely it is to dissociate and form H+ ions, resulting in a substance that is less acidic. This is because a stronger bond requires more energy to break. Inversely, a weaker bond means that the bond is more easily broken to form H+ ions, which translates to greater acidity. For instance, in the series of hydrogen halides (HF, HCl, HBr, HI), as you go down group 17 of the periodic table, bond strength decreases which corresponds with an increase in acidity. Thus, bond strength and binary acidity are inversely related.
