When metallic sodium is dissolved in liquid sodium chloride, electrons are released into the liquid. these dissolved electrons absorb light with a wavelength near 800 nm. suppose we treat the positive ions surrounding an electron very crudely as defining a three-dimensional cubic box of edge l, and we assume that the absorbed light excites the electron from its ground state to the first excited state. calculate the edge length l within this simple model.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
