Question

Hydrochloric acid + Sodium hydroxide (base) 􏰀Sodiumchloride (salt) + Water
Sodium chloride formed in this reaction remains in solution form. Can we get solid sodium chloride from this solution?
Suggest a method

Answer 1

Here's your reaction

\[HCl + NaOH ---> NaCl + H2O \]

Answer 2

Let's take two things into account: #1 this reaction most likely takes place in water (aq)

let's look at our reactants, we have a strong acid HCl and a strong base, what does this mean? a strong acid will completely dissociate from HCl---> H+ and Cl-. why is this good? well because for our reaction we know that virtually all of our acid will be gone leaving no HCl left, b.c it's so strong ka >>>1. the same thing applies for the base. this reaction will virtually go to completion.

That's good because it makes separation easier, meaning we only have to separate NaCl from water. let's just say that we had a weak acid, there would probably be some weak acid left in your flask, along with some salt, and separation would take more steps. in my opinion.

to separate these compounds let's consider one thing. We could probably use something like distillation, which is we manipulate the difference in boiling points of two substances and use the difference to separate them.

so we can boil off all the water, and the salt will be left behind.

I guess that's the only thing I can think of.
