Similarly, the muscles that maintain our posture contract and relax in a synchronized fashion. If the spasm is forceful and sustained, it becomes a cramp. A muscle cramp is an involuntarily and forcibly contracted muscle that does not relax. Muscle cramps cause a visible or palpable hardening of the involved muscle. Muscle cramps can last anywhere from a few seconds to a quarter of an hour or occasionally longer.
CH3COOH is the chemical formula for acetic acid (vinegar). It is also called ethanoic acid. It is considered to be a weak acid as it is only a partially dissociated acid in water.
Some common acids that are found in laboratories are Hydrochloric acid (HCl), Sulphuric acid (H2SO4) and Nitric acid (HNO3). Some of the lesser used acids are Acetic acid (CH3COOH), Hydrofluoric acid (HF), Carbonic acid (H2CO3).Hydrofluoric acid is a highly corrosive acid and is used to etch glass.Some acids are found in nature, like citric acid in certain fruits. These acids are called 'organic acids'.ome common acids that are found in laboratories are Hydrochloric acid (HCl), Sulphuric acid (H2SO4) and Nitric acid (HNO3).
