Unformatted text preview: Strong acids- just memorize them= HCL Hydrochloric HBr Hydrobromic HI Hydroiodic HClO4 Perchloric All Dissociate 100% HClO3 Chloric H2SO4 Sulfuric HNO3 Nitric What is the pH of a 0.5M solution of HBr? Answer is 0.3 should have used a calculator… We can ignore the conjugate base of a strong acid. Strong acids are completely dissociated, you cannot make them go back together. For this reaction which side has a higher entropy? One molecule breaks into two so the products has higher entropy. Look at his examples in his lecture. Liquid water will dissociate only to a small extent. Kw is the water equilibrium, spontaneous dissociation of water. If something has an H+ concentration equal to an OH- concentration we have a neutral solution. If H+ is greater than OH- we have a negative solution. If H+ is less than the OH- solution we have a basic solution. Look at his example slides....
