The image shows a molecular-level representation of part of a solution after HF is dissolved in water. (Besides water, there are 6 HF molecules, 1 H₃O⁺ ion, and 1 F⁻ ion present in the solution.)Which of the following best describes HF? A)strong acid B)strong base C)weak acid D)weak base E)amphoteric

From the image showing the molecular-level representation of HF dissolved in water, we can see that HF (hydrofluoric acid) is a weak acid. This is because it partially dissociates in water to produce H+ ions and F- ions, which are not fully ionized. Strong acids are completely ionized in water, while weak acids are only partially ionized.
