Transition metals can have multiple oxidation states because of their electrons. The transition metals have several electrons with similar energies, so one or all of them can be removed, depending the circumstances. ... When they attach to other atoms, some of their electrons change energy levels.
Our sense of taste is also known as GUSTATION.
Gustation is defined as the act or sensation of tasting.
Both gustation and olfaction are identified as the chemical senses. Olfaction is the sense of smell.
The stimuli for taste are chemical substances that are dissolved in water or any other liquid. You can identify these substances based on four basic sensations which are sweet, sour, bitter, and salty.
Any buffer exists in this equilibrium
HA <=>
In a buffer, there is a large reservoir of both the undissociated acid (HA) and its conjugate base (
)
When a strong acid is added, it reacts with the large reservoir of the conjugate base (
) forming a salt and water. Since this large reservoir of the conjugate base is used, the ph does not alter drastically, but instead resist the pH change.
