Ion-exchange resins are categorized by the nature of functional groups attached to a polymeric matrix, by the chemistry of the particular polymer in the matrix, and by the porosity of the polymeric matrix. There are four primary types of functionaHty strong acid, weak acid, strong base, and weak base. Another type consists of less common stmctures in specialty resins such as those which have chelating characteristics. [Pg.371]

PK. — the negative logarithm of the equilibrium constant for acids or bases. This parameter is an indicator of the strength of an acid or base. Strong acids, such as H2SO4, and HCl, have low pK s (i.e., -1.0) while strong bases such as KOH and NaOH, have pK s close to 14.0. Weak acids and weak bases fall in the intermediate range. [Pg.162]

As noted earlier, ion-exchange materials are grouped into four specific classifications depending on the functional group attached strong-acid cation, strong-base anion, weak-acid cation, or weak-base anion.. In addition to these, we also have inert resins that do not have chemical properties. [Pg.381]

You are asked to determine whether an unknown white solid is acidic or basic. You also need to say whether the add or base is weak or strong. You are given the molar mass of the solid and told that it is soluble in water. Describe an experiment that you can perform to obtain the desired characteristics of die white solid. [Pg.381]

The organic resin material is often a styrene divinylbenzene (DVB) copolymer in a network or matrix, to which are attached functional groups such as a sulfonic acid, carboxylic acid, and quaternary ammonium. The nature of these groups determines whether the resin is classified as a strong/weak acid (cation resin) or strong/weak base (anion resin) ion-exchanger. [Pg.327]

Below is the titration curve for the neutralization of 25 mL of a base with a strong monoprotic acid. Answer the following questions about the reaction and explain your reasoning in each case, (a) Is the base strong or weak (b) What is the initial hydroxide ion concentration of the base (c) What is Kh for the base (d) What is the initial concentration of the base (e) What is the concentration of acid in the titrant (f) Use Table 11.3 to select an indicator for the titration.

When placed in water, some acids and bases completely ionize, or dissociate into their ions—but others do not. Acids and bases that completely ionize are called strong acids and strong bases. Strong acids are defined as acids that have a pH of 0-4. Strong bases have pH values of 10-14. On the other hand, weak acids and weak bases do not disassociate completely in water. This leads to a pH value that is closer to neutral, because some of the hydrogen ions are still attached to other atoms, decreasing the hydrogen ion concentration. [Pg.41]

In a weak acid or base, the backwards reaction (where ions join to form the acid or base) occurs more often than it does in a strong acid or base. Therefore, with a weak acid or base, some hydrogen and hydroxide ions are released, but there are many more molecules of intact acid or base than there would be with a strong acid or base. Most acids and bases are weak. They do not completely break down in water. [Pg.42]

If an amphiprotic solvent contains an acid and base that are neither mutually conjugate nor are conjugated with the solvent, a protolytic reaction occurs between these dissolved components. Four possible situations can arise. If both the acid and base are strong, then neutralization occurs between the lyonium ions and the lyate ions. If the acid is weak and the base strong, the acid reacts with the lyate ions produced by the strong base. The opposite case is analogous. A weak acid and a weak base exchange protons ... [Pg.64]

Solutions of substances that are good conductors of electricity are called electrolytes. Sodium chloride, the major constituent of seawater, is a strong electrolyte. Most salts, as well as strong acids and bases, are strong electrolytes because they remain in solution primarily in ionic (charged) forms. Weak acids and bases are weak electrolytes because they tend to remain in nonionic forms. Pure water is a nonconductor of electricity. [Pg.809]
