When added small amount of strong acid the changes of buffer solution concentration has to be discussed. Concept Introduction: A buffer is an aqueous solution containing substances that prevent major changes in solution pH when small amounts of acid or base are added to it. pH definition: The concentration of hydrogen ion is measured using pH scale. The acidity of aqueous solution is expressed by pH scale. The value pH of a solution is defined as the negative base-10 logarithm of the hydrogen or hydronium ion concentration. pH = -log[H 3 O + ] Based on the pH value, a solution can be classified as acidic, basic or neutral solution. pH < 7, acidic solution pH > 7, basic solution pH = 7, neutral solution Strong acid: In strong acids, the ionization of acid is complete. This implies that the concentration of the hydrogen ion or hydronium ion will be equal to the initial concentration of the acid at equilibrium. Weak acid: In weak acids, the ionization of acid is not complete. This implies that the concentration of the hydrogen ion or hydronium ion will not be equal to the initial concentration of the acid at equilibrium. For strong acids the concentration of acid will be same as that of the concentration of hydrogen ions, because strong acids undergo complete ionization. In case of weak acid, the concentration of hydrogen ion will be less than the concentration of given acid; since weak acid does not ionize completely.

Solution Summary: The author explains that aqueous solutions can be classified as acidic, basic or neutral. Strong acids undergo complete ionization and weak acid does not.
In strong acids, the ionization of acid is complete. This implies that the concentration of the hydrogen ion or hydronium ion will be equal to the initial concentration of the acid at equilibrium.
Weak acid:
In weak acids, the ionization of acid is not complete. This implies that the concentration of the hydrogen ion or hydronium ion will not be equal to the initial concentration of the acid at equilibrium.
For strong acids the concentration of acid will be same as that of the concentration of hydrogen ions, because strong acids undergo complete ionization.
In case of weak acid, the concentration of hydrogen ion will be less than the concentration of given acid; since weak acid does not ionize completely.
These are in the wrong boxes. Why does the one on the left have a lower molar mass than the one on the right?
SYNTHESIS REACTIONS. For the following reactions, synthesize the given products from the given reactants.
Multiple reactions/steps will be needed. For the one of the steps (ie reactions) in each synthesis, write out the
mechanism for that reaction and draw an energy diagram showing the correct number of hills and valleys for
that step's mechanism.
