Q: Is alkalinity the capacity of water to resist changes in pH that would make the water more acidic? ¶
A: Yes.
Q: Is alkalinity modeled and quantified with respect to the CO2 equivalence point? ¶
A: Yes.
Q: Is alkalinity the hydronium cations which exist to balance electrically the increase in calcium anions in deep ocean water? ¶
A: Yes, although now the meaning alkalinity has expanded.
Q: Is alkalinity measured with respect to the CO2 equivalence point? ¶
A: Yes, and the dissolution of CO2, although it adds acid and dissolved inorganic carbon, does not change the alkalinity.
Q: Is alkalinity sometimes incorrectly used interchangeably with basicity? ¶
A: Yes.
Q: Is alkalinity the strength of a buffer solution composed of weak acids and their conjugate bases? ¶
A: Yes.
Q: Is alkalinity measured by adding a strong acid until all the anions listed above are converted to uncharged species? ¶
A: Yes.
Q: Is alkalinity primarily a term used by oceanographers it is also used by hydrologists? ¶
A: Yes.
Q: Is alkalinity typically reported as mg/L as CaCO3? ¶
A: Yes.
Q: Is alkalinity equal to the stoichiometric sum of the bases in solution? ¶
A: Yes.
Q: Is alkalinity a concentration value? ¶
A: Yes, and increasing the volume would theoretically serve to decrease AT.
Q: Is alkalinity expressed in units of meq/L? ¶
A: Yes, and which corresponds to the amount of monoprotic acid added as a titrant in millimoles per liter.
Q: Is alkalinity important in determining a stream's ability to neutralize acidic pollution from rainfall or wastewater? ¶
A: Yes.
Q: Is alkalinity relatively stable, so significant changes can only occur over long time scales? ¶
A: Yes, As a result, seasonal and annual variability is generally very low.
