acidity constant造句

• I have the acidity constant for a hydrazoic acid ( HN3 ) . is that used to write the balanced equation?
• The equation, derived from the acidity constant, states that when pH equals the p " K " a value of the indicator, both species are present in a 1 : 1 ratio.
• In order to obtain a pH-independent constant, the product of the intrinsic Henry's law constant H ^ { cp } and the acidity constant K _ \ text { A } is often used for strong acids like hydrochloric acid ( HCl ):
• This really only comes into play when you're looking for a very accurate measure of the pH . Standard procedure is to assume the first hydrogen dissociates completely, look up the acidity constant for HSO 4-and calculate the concentration of H +, add them together and voila.
• Whereas this apparent p " K " a is quoted as the dissociation constant of carbonic acid, it is ambiguous : it might better be referred to as the acidity constant of dissolved carbon dioxide, as it is particularly useful for calculating the pH of CO 2-containing solutions.
• Malic acid can be further reduced during the winemaking process through malolactic fermentation or MLF . In this process, bacteria convert the stronger malic acid into the softer lactic acid; formally, malic acid is acidity constant ( pK a ) of malic acid ( 3.4 at room temperature ) is lower than the ( single ) acidity constant of lactic acid ( 3.86 at room temperature ), indicating stronger acidity.
