Arrhenius Acids and Bases

More on Arrhenius Bases and Acids Certain ionic compounds with anions other than hydroxide are weak Arrhenius bases Sodium acetate NaC 2 H 3 O 2 is an example When it dissolves it forms sodium ions Na + and acetate ions C 2 H 3 O 2- The latter react with water in a reversible fashion to form acetic acid molecules HC 2 H 3 O 2 and hydroxide ions OH-

Weak acid

A weak acid is an acid that does not fully ionize in solution that is if the acid was represented by the general formula AH then in aqueous solution a significant amount of undissolved AH still remains HA (aq) math leftrightarrow math H + (aq) + A-(aq) The equilibrium concentrations of reactants and products are related by the Acidity constant expression (K a): K a = [H +][A-]/[HA]

Why are there no weak acid

12 12 2014While you can physically titrate a weak base with a weak acid the technique is not useful from a chemical analysis point of view Due to their low Ka/Kb values any disassociation would be small so one would need to add a lot of titrant as well the chemical kinetics to consider For this course we are limiting ourselves to the titrants being strong acids/bases

What Is the Difference Between a Strong Acid and a Weak

A strong acid is one that is 100 percent ionized in a solution and a weak acid is one that doesn't ionize fully when dissolved in water Sulfuric acid is an example of a strong acid and hydrogen fluoride is a weak acid Strong and weak acids are not the same as concentrated and diluted acids An acid's strength is related to how it reacts in

Strong Acids and Weak Acids

Strong acids dissociate completely in water while weak acids do not dissociate completely A classification based on acidity constants or pK a values seems natural Let's denote the total amount of the acid by C T ≡ [HA] T (which is de facto the acid's initial concentration before it dissolves) In the equilibrium state the total concentration splits into its undissociated and
