The K{eq}_a {/eq} of a monoprotic weak acid is 6.70 {eq}\times {/eq} 10{eq}^{-3} {/eq}. What is the percent ionization of a 0.149 M solution of this acid? Weak Acid and Degree of Dissociation A weak acid is defined as the ...
A weak Arrhenius acid (e.g. acetic acid) is distinguished from a strong one (e.g. HCl) by its limited dissociation inside an aqueous solution. An equilibrium state is reached where most of the starting weak acid molarity is still present. Therefore, the dissociation (equilibrium) const...
Acids are characterized as weak or strong based on their extent of dissociation or percent ionization. This is also related to the dissociation constant of that acid which is directly proportional to the square of the degree of ionization at a specif...
