the pKa of acetic acid CH3COOH is 4.75.? | Yahoo Answers

Jun 24, 2009· If the acetate/acid ratio is 10:1, the log term is 1, so pH = pKa + 1, or 5.75. Conversely, if it''s 0.1, the log term becomes -1, and the pH = 3.75. 0 0. Still have questions? Get your answers by asking now. Ask Question + 100. Join Yahoo Answers …

acid). However, the physical measurement of the basicity of an industrial slag is still not possible, even in these modern times. A nuer of formulations have been used to express the basicity of a slag. The most common approach is the use of a basicity index in which the basic oxides are placed on the numerator and the acid oxides on the

The blockade of lipophagy pathway is necessary for

However, the regulatory network of LD disappearance is still unclear. It has been reported that lipophagy activation contributed to LD loss by upregulating RAB25 expression. In the present study, we sought to determine the regulation of docosahexaenoic acid (DHA) on LD disappearance, and to further examine potential molecular mechanisms.

Arsenic in Samples Prepared by OSHA Method ID-125 ()The purpose of this experiment was to determine if the arsenic spiked onto MCE filters could be recovered after using the sample preparation suggested in OSHA method ID-125 ().This is an ICP method which used 4% H 2 SO 4 and 4% HCl as the acid matrix for analysis [Note: The current ICP methods use 4% H 2 SO 4 …

Ionization Constants of Organic Acids

Because of the very large range of acid strengths ( greater than 10 40), a logarithmic scale of acidity ( pK a) is normally employed.Stronger acids have smaller or more negative pK a values than do weaker acids. A discussion of acid-base terminology is available here. The pK a values given here are extrapolated for water at 25 ºC. Many of the pK a values given for weak carbon acids are
