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.
H2CO3 is a weak acid and its conjugate base must be a strong base, H2CO3 = H+(aq) + HCO3-(aq) Eq Constant value is too low the products will not dominate, the reaction has hardly proceded to forward direction. i.e HCO3- ion has great tendency to take up proton thus a strong base.trong acids/bases give rise to weak conjugate bases/acids Weak acids/bases give rise to strong conjugate bases/acids That's just because an equilibrium that is very much in favour of one is very much against the other. (Original post by jsmith6131). HCO3- is the strong conjugate base of H2CO3. HCO3- = CO3 2- + H+.
