Concept explainers
Interpretation:
Acid-base equilibria connecting all components in the aqueous solution of formic acid have to be written and all of the species present has to be listed
Concept introduction:
Acid:
According to Bronsted-Lowry theory, a species which donates a proton in a proton transfer-reaction is said to be an acid.
Base:
According to Bronsted-Lowry theory, a species which accepts a proton in a proton transfer-reaction is said to be base.
Acid-base equilibria:
Acid-base equilibria which describes the Arrhenius theory, Bronsted-Lowry theory, and Lewis theory of acids and bases and explains the relationship between them.

- Acids You make a solution by dissolving 0.0010 mol of HCl in enough water to make 1.0 L of solution. a Write the chemical equation for the reaction of HCl(aq) and water. b Without performing calculations, give a rough estimate of the pH of the HCl solution. Justify your answer. c Calculate the H3O+ concentration and the pH of the solution. d Is there any concentration of the base OH present in this solution of HCl(aq)? If so, where did it come from? e If you increase the OH concentration of the solution by adding NaOH, does the H3O+ concentration change? If you think it does, explain why this change occurs and whether the H3O+ concentration increases or decreases. f If you were to measure the pH of 10 drops of the original HCl solution, would you expect it to be different from the pH of the entire sample? Explain. g Explain how two different volumes of your original HCl solution can have the same pH yet contain different moles of H3O+. h If 1.0 L of pure water were added to the HCl solution, would this have any impact on the pH?
