☆☆☆☆☆the function of a buffer is to maintain the pH of the sample.
Suppose: B- is symbol for any (soluble) base.
Equilibrium of a base when diluted in water:
B- + H2O <==> HB + OH-
Equilibrium constant:
Keq = [HB] * [OH-] / [B-] * [H2O]
The base dissociation contant is defined by:
KB = [HB]*[OH-]/[B-]So, KB = Keq*[H2O] = Keq*55.6 mol/L

Patients should be treated with humble and love like the way babies are treated.
some of the acid has dissociated

The Le Chtelier's principle states one thing. It is the dynamic equilibrium which is disturbed by changing the conditions and the position of equilibrium moves that makes a change.
The reaction would shift to balance the change
The information an acid or base equilibrium constant gives is that the acidity and base levels are equal to the equilibrium constant multi[plied by the water concentration.
pH of a solution tells us about the nature of a solution( i.e acidic or basic ) if pH of a solution is less than 7 tahn it's acidic if it's 7 then it's neutral and more than seven will make it base.
Identify a need, research the background, make a plan, do the work, evaluate the results, look for improvements. (APEX)
This is called molality.
The dissociation constant is:
k = [H][X]/[HX]
I suppose that the principle of Le Châtelier is not applicable in this case.
These concentrations are supposed to be equal.
look at the success rate of the current treatments
pH = -log [H+(aq)]. In words, pH is the negative logarithm (to the base 10) of the hydrogen ion concentration.
Testing the composite drug in a trial run.
pH=-log[H+]
Edited: it is also pH = 14 - pOH. That is certainly an equation for pH.
