WebJul 10, 2024 · Comparable replacement: ΔH lattice(CaO) = −3464 kJ/mol. Compare that to these: ΔH lattice(KBr) = −688 kJ/mol. ΔH lattice(CsI) = − 604 kJ/mol. So, we were correct. The larger negative value we have for the lattice energy, the more energy released when the lattice was formed, and thus the stronger the lattice structure and the higher the ... WebSep 1, 2024 · A strong acid is one which completely dissociates in its solvent. Under most definitions, the acid dissociates into a positively-charged hydrogen ion (proton) and a negatively-charged anion. The seven most common strong acids are hydrochloric acid, nitric acid, sulfuric acid, hydrobromic acid, hydroiodic acid, perchloric acid, and chloric acid.
