Consider the following data on some weak acids and weak bases: Use this data to rank the following solutions in order of increasing pH. And then, for the concentration of acetate at equilibrium, concentration of acetate is zero point two five minus X. One "rule of thumb" that I learned is if your x ends up being larger than 5% of your starting value you need to solve the quadratic. So are we to assume it dissociates completely?? Salts that form from a weak acid and a strong base are basic salts, like sodium bicarbonate (NaHCO3). is titrated with 0.300 M NaOH. So X is equal to the Explain.
