In a 100 mL (3 + 1 ⁄ 2 US fl oz) reference amount, distilled vinegar supplies 75 kJ (18 kcal) of food energy and no micronutrients in significant content. [45] The composition (and absence of nutrient content) for red wine vinegar and apple cider vinegar are the same, whereas balsamic vinegar is 77% water with 17% carbohydrates, 370 kJ (88 ...
The very ambiguous terms "percent solution" and "percentage solutions" with no other qualifiers, continue to occasionally be encountered. This common usage of % to mean m/v in biology is because of many biological solutions being dilute and water-based, an aqueous solution. Liquid water has a density of approximately 1 g/cm 3 (1 g/mL). Thus 100 ...
In aqueous solution, it has a pK a value of 4.76. [21] Its conjugate base is acetate (CH 3 COO −). A 1.0 M solution (about the concentration of domestic vinegar) has a pH of 2.4, indicating that merely 0.4% of the acetic acid molecules are dissociated. [a] Cyclic dimer of acetic acid; dashed green lines represent hydrogen bonds

CH 3 COONa + BrCH 2 CH 3 → CH 3 COOCH 2 CH 3 + NaBr. Sodium acetate undergoes decarboxylation to form methane (CH 4) under forcing conditions (pyrolysis in the presence of sodium hydroxide): CH 3 COONa + NaOH → CH 4 + Na 2 CO 3. Calcium oxide is the typical catalyst used for this reaction. Cesium salts also catalyze this reaction. [citation ...
Percentage solution may refer to: Mass fraction (or "% w/w" or "wt.%"), for percent mass; Volume fraction (or "% v/v" or "vol.%"), volume concentration, for percent volume "Mass/volume percentage" (or "% m/v") in biology, for mass per unit volume; incorrectly used to denote mass concentration (chemistry). See usage in biology
As an eardrop it is used to treat infections of the ear canal. [1] It may be used with an ear wick. [2] As a liquid it is used to flush the bladder in those who have a urinary catheter in an attempt to prevent infection or blockage. [3] As a gel it may be used to adjust the pH of the vagina. [4]
