How will you prepare a pH 4.50 acetic acid-acetate buffer such that when 1.00 mL of 10 M NaOH is added to 100.00 mL of this buffer, the resulting pH will be raised by exactly 1 pH unit? Show calculations for the concentrations (in 3 decimal places) of the components that must be present in the buffer as well as the volumes of 1 M acetic acid and 1 M sodium acetate that need to be mixed and diluted to 100.00 mL to prepare the buffer. (There is no specific final buffer concentration required here. You can verify your answers by using the Virtual Lab).

Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.
