WebbSince it is inconvenient to have to say or to remember Ka values like 1.8×10 -5, pKa is used more often in Organic Chemistry to refer to the relative acidity of different acids. The definition of p K a is: p Ka = -log Ka The smaller the pKa value, the larger the Ka, and the stronger the acidity is. The p Ka of most organic acids range between 5~60. WebbBuffer Index (BI) measured in the laboratory, as a part of the Oklahoma State University soil test, is an indirect estimate of the soil reservoir size for storing basic material.
