Hey everyone today we're being asked to determine if N. A. O. C. L. Or sodium hypochlorite would form an acidic neutral or basic solution when dissolved in water. So let's write this out when sodium hypochlorite, N. A. O. C. L. Is dissolved in water. You can write this as a quiz. It will form And associate into two separate ions. We will get the sodium cat on an A. Plus and we'll get the hipaa chloride and I hunt the O. C. L. Minus and I on. So let's take a look first at the sodium plus ion the Canada. So as a general rule of thumb, main group metal cat ions similar to N. A. Plus can be acidic if they have a charge of three plus or more. However sodium is a group one metal. It is an alkali metal and it only has a plus one charge Since it doesn't have a charge greater than 3-plus it will be neutral. So in a. Plus the sodium cat ion is a neutral is a neutral, carry on. Cat eye on. So that leaves us with the hypochlorite. An ion. Oh cl minus. Now if we actually take a closer look at hyper chloride we can see that it's actually the conjugate base of a weak acid of hypochlorite acid. And let's write this out. Oh cl minus where to react with water. H 20 liquid. We would get h O cl plus hydroxide where h oh cl is a hyper caloric acid is a weak acid hydroxide is the base. Which means hypochlorite is the conjugate base of the weak acid hydrochloric acid. Since it is a conjugate base, this inherently means that it is basic. An ion, furthermore being an an ionic can donate electron pairs or electrons to other elements or compounds in the solution, defining it as a lewis base as well. But it is a basic and I As such since one ion is neutral, but the other is basic. This means that sodium hyper chloride or N A O C L oh cl would form a basic solution, a basic solution solution oops solution when dissolved in water. I hope this helps and I look forward to seeing you in the next one.
