A Is For Acid (MPIA3 Definition)

Here, water acts as an acid and a base at the same time. Such substances are named ampholytes. The proton-transfer mechanism makes acid-base reactions very fast, so that chemical equilibrium is always established in the shortest time. This allows the application of a thermodynamic description while slow reactions, such as redox processes, require more sophisticated kinetic approaches. The value of K a resembles the strength of the acid large K a — strong acids, small K a — weak acids. In practice, it is more convenient to use the base logarithmic form of 5 :.

Most acids contain a hydrogen atom bonded that can release dissociate to yield a cation and an anion in water. The higher the concentration of hydrogen ions produced by an acid, the higher its acidity and the lower the pH of the solution.

The word acid comes from the Latin words acidus or acerewhich mean "sour," since one of the characteristics of acids in water is a sour taste e.

These are examples of types of acids and specific acids:.

Acids may be identified as either strong or weak based on how completely they dissociate into their ions in water. A given amount of an acid added to the same amount of a base neutralizes the base, producing water and a A Is For Acid (MPIA3 Definition). Common vinegar, for example, is a weak solution of acetic acid. New Word List Word List. Save This Word! See synonyms for acid on Thesaurus.
