Strong Acids/ Bases

Strong Acids/ Bases. Strong Acids more readily release H+ into water, they more fully dissociate H 2 SO 4 ? 2 H + + SO 4 2- Strong Bases more readily release OH- into water, they more fully dissociate NaOH ? Na + + OH - Strength DOES NOT EQUAL Concentration!. Acid-base Dissociation.

THE RELATIONSHIP BETWEEN H 2 CO 3 * AND HCO 3 -

THE RELATIONSHIP BETWEEN H 2 CO 3 * AND HCO 3 -. We can rearrange the expression for K 1 to obtain: This equation shows that, when pH = p K 1 , the activities of carbonic acid and bicarbonate are equal. We can also rearrange the expression for K 2 to obtain:

The common ion effect Ch 3 COOH + H 2 O ?CHCOO - + H 3 O + If we add crystalls of CH 3 COONa

The common ion effect Ch 3 COOH + H 2 O ?CHCOO - + H 3 O + If we add crystalls of CH 3 COONa The concentration of CH 3 COO _ Will increase the equilibrium will shift to the left , thus the concentration H 3 O + will decrease and pH will increase. Example:
