Acetic acid can never be truly water-free in an atmosphere that contains water, so the presence of 0.1% water in glacial acetic acid lowers its melting point by 0.2 °C. [ 9 ] A common symbol for acetic acid is AcOH (or HOAc), where Ac is the pseudoelement symbol representing the acetyl group CH 3 −C(=O)− ; the conjugate base , acetate ( CH ...
Vinegar is known as an effective cleaner of stainless steel and glass. Malt vinegar sprinkled onto crumpled newspaper is a traditional, and still-popular, method of cleaning grease-smeared windows and mirrors in the United Kingdom. [53] Vinegar can be used for polishing copper, brass, bronze or silver.
Traditional balsamic vinegar is produced from the juice of just-harvested white grapes, typically, Trebbiano grapes, boiled down to reach a minimum sugar concentration of 30% (brix) or more in the must, which is then fermented with a slow ageing process which further concentrates the flavours. The flavour intensifies over the years, with the ...
Dogs are prone to have adverse allergic reactions to food similar to human beings. The most common symptoms of food allergies in dogs include rashes, swelling, itchy or tender skin, and gastrointestinal upsets such as uncontrollable bowel movements and soft stools. [82] Certain ingredients in dog food can elicit these allergic reactions.
A few studies asked their guardians to report on their dogs' health. Fewer vegetarian or vegan dogs were reported to have been suffering from healthcare problems compared to those on a conventional diet. [30] Specific benefits such as a better coat condition, animal scent, and others are reported as well. [3] [31]
Photographic developers are alkaline, so a mild acid is used to neutralize and stop their action quickly, but commonly used acetic acid leaves a strong vinegar odor in the darkroom. [41] Citric acid is an excellent soldering flux, [42] either dry or as a concentrated solution in water. It should be removed after soldering, especially with fine ...
30% Hydrochloric acid. Of the common strong mineral acids in chemistry, hydrochloric acid is the monoprotic acid least likely to undergo an interfering oxidation-reduction reaction. It is one of the least hazardous strong acids to handle; despite its acidity, it contains the non-reactive and non-toxic chloride ion.
As dogs grow older, their performance and ability to learn new smells is reduced. Female dogs have a greater sense of smell than males. A variety of diseases can decrease a dog's sense of smell, such as canine distemper and nasal mites. Dogs have an enhanced sense of smell when fed a high-fat, low-protein diet. There are a number of theories ...
