The general formula of an unknown salt is given to be BHCl where B a weak base is. The pH value of a 0.10 M solution of the unknown salt is 5.82 . The actual formula of the salt is to be stated. Concept introduction: The pH of a solution is define as a figure that expresses the acidity of the alkalinity of a given solution. The pH of a solution is calculated by the formula, pH = − log [ H + ] The sum, pH + pOH = 14 The equilibrium constant for water is denoted by K w and is expressed as, K w = [ H + ] [ OH − ] The value of K w is calculated by the formula, K w = K a ⋅ K b

Interpretation: The general formula of an unknown salt is given to be
BHCl where
B a weak base is. The
pH value of a
0.10M solution of the unknown salt is
5.82. The actual formula of the salt is to be stated.
Concept introduction: The
pH of a solution is define as a figure that expresses the acidity of the alkalinity of a given solution.
The
pH of a solution is calculated by the formula,
pH=−log[H+]
The sum,
pH+pOH=14
The equilibrium constant for water is denoted by
Kw and is expressed as,
20. The Brusselator. This hypothetical system was first proposed by a group work-
ing in Brussels [see Prigogine and Lefever (1968)] in connection with spatially
nonuniform chemical patterns. Because certain steps involve trimolecular reac
tions, it is not a model of any real chemical system but rather a prototype that
has been studied extensively. The reaction steps are
A-X.
B+X-Y+D.
2X+ Y-3X,
X-E.

It is assumed that concentrations of A, B, D, and E are kept artificially con
stant so that only X and Y vary with time.
(a) Show that if all rate constants are chosen appropriately, the equations de
scribing a Brusselator are:
dt
A-(B+ 1)x + x²y,
dy
=Bx-x²y.
