Question

BeWhat direction do you predict the addition of a base to the solution containing bromophenol blue will drive the equilibrium? Explain your prediction in terms of le chatelier principle

Answer 1

Answer:

Explanation:

Le Chatlier's principle expresses that when a system in equilibrium is irritated by outside changes, the system reacts by altering the equilibrium concentrations of its segments to such an extent that the annoyance is invalidated and accomplishes an equilibrium state at this bothered condition, with equilibrium concentrations not quite the same as in the past.

Bromothymol blue is a phenolic suflone that demonstrations a weak acid in aqueous media. Being a weak acid, it doesn't ionize totally and builds up a harmony with its related and separated structure.

From Le Chatlier's guideline, it very well may be found out that when a strong acid is included, the last's finished separation, without foundation of equilibrium causes a spike in the proton concentration in the medium. This expansion in proton concentration is the outer bother and the framework will react by shifting to one side, consequently protonating more dianions of bromothymol with an end goal to invalidate the proton concentration increment.  

Thus, when a base is included, it devours the protons in the medium to shape water. In this way, the concentration of protons in the medium declines. To repay this change, the equilibrium reacts by shifting to the privilege i.e., it makes a greater amount of the unbiased pointer separate into the dianion and protons, hence endeavors to invalidate the bother.
