Ground limestone (lime) is usually used to increase the pH of acid soils, thus making them less acid. The amount of lime needed depends on a number of factors, such as the current acidity level of the soil, the quality of the limestone and the soil it is applied to. The only really accurate way to know how much lime is required is to have a soil test done.

Example 13 A raw water containing 140 mg/L of dissolved solids is subjected to a coagulation treatment using Fe2(S04)3. For optimum coagulation, the pH should be raised to 8.2. The current acidity is 6.0(10 jgeq/L and the current pH is 8.0. Calculate the amount of lime needed, assuming [Pg.76]

A raw water is subjected to a coagulation treatment using FeC. The current acidity and pH are, respectively, 30 mg/L as CaC03 and 5.9. The sohds produced amount to 0.132 kg/m of water treated. What was the suspended solids content of the raw water, if the optimum coagulant dose is 40 mg/L ...

Rychtman, A New View of Current Acid-Base Theories, John Wiley Sons, New York, 1982, provide good overviews of the history of acid-base theories and critical discussions of the different theories. R. G. Pearson s Hard and Soft Acids and Bases, Dowden, Hutchinson, Ross, Stroudsburg, PA, 1973, is a review by one of the leading exponents of HSAB.

Often a patient s normal response to these chemical receptors that drive respiration is perturbed by a pathological condition in the circulatory or respiratory system. If significantly abnormal, the patient will require assisted ventilation that uses a mechanical device to provide gas mix-tures intermittently via an endotracheal tube inserted through the mouth or through a tracheostomy. Gas mixtures containing different fractional compositions of O2 and CO2 may be administered in conjunction with assisted ventilation. A physician s adjustments of the conditions of this mechanical ventilation depend greatly on the results of blood gas and pH determinations that reflect current acid-base status.
