Lowest concentration of ethanoate ions

In summary, dilute hydrochloric acid would leave the lowest concentration of ethanoate (acetate) ions when added to an aqueous solution of ethanoic (acetic) acid due to the reaction of ethanoic acid dissociation.

Homework Statement


A small quantity of each of the following is added to separate samples of an aqueous solution of ethanoic (acetic) acid. Which would leave the lowest concentration of ethanoate (acetate) ions?
  1. sodium hydrogen carbonate solution
  2. dilute hydrochloric acid
  3. magnesium
  4. dilute sodium hydroxide solution
  5. ethanol

Homework Equations

The Attempt at a Solution



I chose 2) dilute HCl solution because the reaction of ethanoic acid dissociation is:

CH3COOH ↔ CH3COO- + H+.

If HCl was added, there will be more H+ present so therefore the equilibrium would shift to the left and decrease the concentration of ethanoate ions. Is this correct?

Thanks!

1. What is the lowest concentration of ethanoate ions?

The lowest concentration of ethanoate ions refers to the smallest amount of ethanoate ions present in a solution. It is typically measured in moles per liter (mol/L) or parts per million (ppm).

2. Why is the lowest concentration of ethanoate ions important?

The lowest concentration of ethanoate ions is important because it can affect the properties and behavior of the solution. It can also impact the effectiveness and accuracy of certain experiments or processes that involve ethanoate ions.

3. How is the lowest concentration of ethanoate ions determined?

The lowest concentration of ethanoate ions can be determined through various methods such as titration, spectrophotometry, or ion selective electrodes. These methods involve measuring the amount of ethanoate ions present in a solution and calculating the concentration based on the volume of the solution.

4. What factors can affect the lowest concentration of ethanoate ions?

The lowest concentration of ethanoate ions can be affected by factors such as temperature, pH level, and the presence of other ions or compounds in the solution. These factors can alter the dissociation of ethanoic acid and its salts, which in turn affects the concentration of ethanoate ions.

5. How can the lowest concentration of ethanoate ions be increased or decreased?

The lowest concentration of ethanoate ions can be increased by adding more ethanoic acid or its salts to the solution, or by decreasing the volume of the solution. It can be decreased by diluting the solution with water or by removing some of the ethanoate ions through a chemical reaction or filtration process.
