Get proficient with the General Science concepts with detailed lessons on the topic Chemistry among many others. Acetic acid is an example of a weak electrolyte even though it is highly soluble in water. ELLA MARU STUDIO / SCIENCE PHOTO LIBRARY / Getty Images A weak electrolyte is an electrolyte that does not completely dissociate in aqueous solution. The solution will contain both ions and
molecules of the electrolyte. Weak electrolytes only partially ionize in water (usually 1% to 10%), while strong
electrolytes completely ionize (100%). HC2H3O2 (acetic acid), H2CO3 (carbonic acid), NH3 (ammonia), and H3PO4 (phosphoric acid) are all examples of weak electrolytes.
Weak acids and weak bases are weak electrolytes. In contrast, strong acids, strong bases, and salts are strong electrolytes. Note a salt may have low solubility in water, yet still be a strong electrolyte because the amount that does dissolve completely ionizes in water. Whether or not a substance dissolves in water is not the determining factor in its strength as an electrolyte. In other words, dissociation and dissolution are not the same things. For example, acetic acid (the acid found in vinegar) is extremely soluble in water. However, most of the acetic acid remains intact as its original molecule rather than its ionized form, ethanoate
(CH3COO-). An equilibrium reaction plays a big role in this. Acetic acid dissolves in water an ionizes into ethanoate and the hydronium ion, but the equilibrium position is to the left (reactants are favored). In other words, when ethanoate and hydronium form, they readily return to acetic acid and water: CH3COOH + H2O ⇆ CH3COO- + H3O+ The small amount of product (ethanoate) makes acetic acid a weak electrolyte rather than a strong electrolyte. Which of the following is a weak electrolyte?A. \[N{a_2}C{O_3}\] B. \[KHC{O_3}\] C. \[{(C{H_3}COO)_2}Pb\] D.All of the aboveAnswer Verified Hint: To solve this question, we must understand the meaning and characteristics of a weak electrolyte. Then we need to compare the properties of the compounds given to us to find the correct answer. Complete Step-by-Step Answer: Hence, Option D is the correct option Note: On the other hand, a strong electrolyte is a solution/solute that completely, or almost completely, ionizes or dissociates in a solution. These ions are good conductors of electric current in the solution. What is the formula of weak electrolyte?HC2H3O2 (acetic acid), H2CO3 (carbonic acid), NH3 (ammonia), and H3PO4 (phosphoric acid) are all examples of weak electrolytes. Weak acids and weak bases are weak electrolytes.
Is ch3cooh weak electrolyte?Answer and Explanation: Acetic acid is a weak acid as suggested by its low dissociation constant. This low dissociation constant of acetic acid makes its ionization in an aqueous solution very limited. With this, it can be considered that acetic acid is a weak electrolyte.
Is KCL a weak electrolyte?Solution: Yes, potassium chloride is a strong electrolyte. As it dissociates completely into its ions on dilution.
Why is Na2CO3 a weak electrolyte?Na2CO3 is a weak electrolyte as the solution is partially dissociated in the fused or aqueous solution state. PhNH+3Cl(aq.) Na2CO3(aq.)
