Which of these are weak electrolyes and which are strong ones?or are non-electrolytes?
A strong or weak electrolyte is one that is dissolved in water. HCl as a gas is not an electrolye. An electrolyte is a solution that conducts electricity. The conductivity depends on the relative number of ions in solution. The terms “strong” and “weak” refer to the degree to which the substance dissociates into ions. HCl is a strong acid because it breaks up completely into H+ and Cl-, while acetic acid is a weak acid because it only partially (about 1%) dissociates. HCl – strong when dissolved in water HOAc – weak when dissolved in water NaOH – strong when dissolved in water NH4OH – weak when dissolved in water NH4Cl – strong when dissolved in water NaOAc – strong when dissolved in water NaCl solution – strong Sugar solution – nonelectrolyte Water is a weak electrolyte because it will dissociate to a slight extent to form H+ and OH-. If something is dissolved in water that forms ions, the mixture will be a better electrolyte.
