Suppose you have just added 100 ml of a solution containing 0.5 mol of acetic acid per liter to 400 ml of 0.5 m naoh. what is the final ph? (the pka of acetic acid is 4.7.)

Explanation:

Sodium hydroxide completely ionizes in water to produce sodium ions and hydroxide ions. Hydroxide ions are in excess and neutralize all acetic acid added by the following ionic equation:

The mixture would contain

if undergoes no hydrolysis; the solution is of volume after the mixing. The two species would thus be of concentration and , respectively.

Construct a RICE table for the hydrolysis of under a basic aqueous environment (with a negligible hydronium concentration.)

The question supplied the acid dissociation constant for acetic acid ; however, calculating the hydrolysis equilibrium taking place in this basic mixture requires the base dissociation constant for its conjugate base, . The following relationship relates the two quantities:

... where the water self-ionization constant under standard conditions. Thus . By the definition of :

by cartels in other countries, shipped by air, mail, or land. i cant really see your answer choices : /

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
