| h English (en) | ===Acidity=== Fatty acids do not show a great variation in their acidities, as indicated by their respective [[Acid dissociation constant|p''K''<sub>a</sub>]]. [[Nonanoic acid]], for example, has a p''K''{{sub|a}} of 4.96, being only slightly weaker than acetic acid (4.76). As the chain length increases, the solubility of the fatty acids in water decreases, so that the longer-chain fatty acids have minimal effect on the [[pH]] of an aqueous solution. Near neutral pH, fatty acids exist at their conjugate bases, i.e. oleate, etc. |
| h Japanese (ja) | ===酸度=== 脂肪酸は、それぞれの[[Acid dissociation constant/ja|p''K''<sub>a</sub>]]で示されるように、その酸性度に大きなばらつきはない。例えば[[Nonanoic acid/ja|ノナン酸]]のp''K''{{sub|a}}は4.96で、酢酸（4.76）よりわずかに弱い。鎖長が長くなるにつれて、脂肪酸の水への溶解度は減少するため、鎖長の長い脂肪酸は水溶液の[[pH]]にほとんど影響を与えない。中性[[pH/ja|pH]]付近では、脂肪酸は共役塩基、すなわちオレイン酸塩基などで存在する。 |
