For example, strong acids like sulfuric acid are known to completely dissociate into their ions and are thus very strong conductors in solution. On the other hand, acetic acid is a weak one due to the lower strength of ionization due to its molecular structure. The same goes for a base li...
Why water is a weak electrolyte? Sodium is much more apt to exist as a positive ion than is chlorine. Why does this occur? Why is water a poor conductor of electricity? What is the cancer risk associated with the consumption of 15 grams of chlorine in drinking water? Why is the ...
They can be divided into two groups; strong and weak ion exchange resins depending on the number and the chemical nature of ionic groups contained within the resin. Most drug–resin complexes (so called “resonates”) are prepared by the batch method whereby a certain amount of IER is ...
Equilibrium favors reactants or only a small amount dissociates – a weak base. Write the ionization equation and ionization constant expression for the following acids and bases: a.) HF b.) HBrO c.)NH3 d.) CH3NH2 Example Ka Values for Polyprotic Acids Some acids can donate more ...

acids – all their H+ is dissociated completely in water • Weak acids – dissociate partially in water and are efficient at preventing pH changes • Strong bases – dissociate easily in water and quickly tie up H+ • Weak bases – accept H+ more slowly (e.g., HCO3¯ and NH3) ...
