Solution Summary: The author explains how the pH value of saturated zinc hydroxide is calculated. The acidity or alkalinity of a given solution is expressed by the negative base-10 logarithm
The pH value of saturated zinc hydroxide Zn(OH)2 solution has to be calculated.
Concept introduction:
pH: The concentration of hydrogen ion is measured using pH scale. The pH of a solution is a figure that expresses the acidity or the alkalinity of a given solution.
It is defined as the negative base-10 logarithm of the hydrogen or hydronium ion concentration.
pH=-log[H3O+]
pOH: It is the negative base-10 logarithm of the hydroxide ion [OH-] concentration.
pOH=-log[OH-]
Relationship between pH and pOH is that pH+pOH=14.
Acid dissociation constant Ka represents how strong the acid is in a solution. pKa is defined as negative logarithm of acid dissociation constant(Ka).
pKa=−logKa
The strength of acid decreases as the value of pKa increases
pKa represents the chance of losing proton from a compound.
The solubility product constant (Ksp) is defined as the equilibrium between compound and its ions in an aqueous solution.
Solubility product is the multiplication of concentration of dissolved ion, raised to the power of its coefficients.
For ionic compound A3B, Ksp is denoted as [A]3[B].
