WebWhen they dissociate to form ions, water molecules therefore form a positively charged H + ion and a negatively charged OH - ion. The opposite reaction can also occur H + ions can … WebThe KOH dissociates to form K + and OH - ions. The OH - ions will react with H + ions to form water in a neutralisation reaction. The equilibrium of weak acid: CH3COOH <-> H + + CH3COOH - Will shift its equilibrium position to the right in order to minimise the decreased H + concentration.
WebA stronger acid more readily ionizes, or dissociates, in a solution than a weaker acid. The six common strong acids are: hydrochloric acid (HCl) hydrobromic acid (HBr) hydroiodic acid (HI) sulfuric acid (H 2 SO 4; only the first proton is considered strongly acidic) nitric acid (HNO 3) perchloric acid (HClO 4) WebThe dissociation constant K d is used as indicator of the affinity of the ligand to the receptor. The higher the affinity of the ligand for the receptor the lower the K d value (and the higher …
