Question

How might you explain the difference between the pH values of the 0.01 M HCl (pH = 1.1) and the 0.01 M HC2H3O2 (pH = 3.6)? HCl produces less H+. HCl dissociates more. HC2H3O2 produces both H+ and OH-. HC2H3O2 produces more H+.

Answer 1

Answer;

HCl dissociates more.

Explanation;

• HCl is a strong acid while HC2H3O2 is a weak acid. A strong acid such as HCl ionizes or dissociates completely in an aqueous solution by losing one proton.
• A weak acid is one that does not dissociate completely in solution; this means that a weak acid does not donate all of its hydrogen ions (H+) in a solution. For example; HC2H3O2.
