Trichloroacetic acid is used to treat genital warts. Write the equilibrium reaction for this weak acid in aqueous solution. A) What substances are present at equilibrium? B) Are the concentrations of the acid and constant or changing at equilibrium? C) What happens to the equilibrium if more trichloroacetate is added to the reaction? D) If more hydronium ions are added to the reaction, does the reaction shift to the left or right?

Homework Answers

Answer #1

a)

the equilibrium is given by

CCl3COOH + H20 ----> H30+ + CCl3COO-

b)

at equilibrium

the concentration of acid is constant

c)

CCl3COOH + H20 ----> H30+ + CCl3COO

now

we know that

according to Lechatlier principle

the equilibrium will shift in such a direction to counter the change

given

more CCl3COOH is added ,

so

the conc of CCl3COOH is increased

so

the equilibrium will shift in a direction to decrease the conc of CCl3COOH

so

the equilibrium will shift towards the products


d)

similarly

the conc of H30+ is increased

so

the equilibrium will shift to the left to decrease the conc of H30+

The common-ion effect and buffer systems A buffer is a mixed solution of a weak acid or base, combined with its conjugate. Note that this can be understood essentially as a common-ion problem: The conjugate is a common ion added to an equilibrium system of a weak acid or base. The addition of the conjugate shifts the equilibrium of the system to relieve the stress of the added concentration of the common ion. In a solution consisting of a weak...

Assume you dissolve 0.235g of the weak acid benzoic acid in enough water to make 1.00*102 mL of soultion and then titrate the solution with 0.108M NaOH. What is the pH at the equivalence point? When 1.55g of solid thallium(I) bromide is added to 1.00L of water, the salt dissolves to a small extent TlBr\left(s\right)\longleftrightarrow Tl^+\left(aq\right)+Br^-\left(aq\right). The thallium(I) and bromide ions in equilibrium with TlBr each have a concentration of 1.9*10-3 M. What is the value of pKsp for TlBr?
Percent ionization can be used to quantify the extent of ionization of an acid in solution...
Percent ionization can be used to quantify the extent of ionization of an acid in solution and is defined by the following formula for the acid HA: Percent ionization=[HA] ionized[HA] initial×100% Percent ionization increases with increasing Ka. Strong acids, for which Ka is very large, ionize completely (100%). For weak acids, the percent ionization changes with concentration. The more diluted the acid is, the greater percent ionization. A convenient way to keep track of changing concentrations is through what is...

When a solution contains a weak acid and its conjugate base or a weak base and its conjugate acid, it will be a buffer solution. Buffers resist change in pH following the addition of acid or base. A buffer solution prepared from a weak acid (HA) and its conjugate base (A−) is represented as HA(aq)⇌H+(aq)+A−(aq) The buffer will follow Le Châtelier's principle. If acid is added, the reaction shifts to consume the added H+, forming more HA. When base is...
