 Okay, so this question is just like the last one, it says predict whether the aqueous solution of sodium benzoate is going to be acidic, basic, or neutral So if you recall, how did we figure out what we did last time, or how did we figure out what the solution was last time? We pretended to put this in the water and break it up So what would it break up to? Can you help me? S H 5 C O O C O O Minus, very good Plus what? Na plus Na plus, okay And if you recall the last time, when we talked about potassium, which is in the same family as sodium, same period as sodium, right? When we talked about potassium, we were saying, well that cation came from, do you remember, a strong base? So this would be, what strong base would this one come from? NaOH NaOH, yeah, very good Okay, so then what would this be a conjugate base of? So this would be the conjugate base of some acid, right? Carboxylic acid A carboxylic acid, very good In this case it's benzoic acid, but not that you need to know that since you're in jim camp And that would be? A weak acid A weak acid, right? And this is the strong base So remember what we said, when we have a strong base and a weak acid react together, right? What's going to happen? Well, we're going to get something that looks like this And then these things, right? This thing is not going to be able to react with water, just like the potassium was But this thing, right, is the conjugate base of this acid So when we add this to water, right? Remember, these weak acids, they're in equilibrium with their conjugate acid and conjugate base So when we add that to water, what happens? We're going back and forth like that, okay? So when we add that to water, what do we get, right? We're going to get this, plus OH minus, right? Because we remove one hydrogen from water and add it to this thing, right? We got this carboxylic acid What happens to the rest of water? It becomes this OH minus here, okay? What does that do when you have OH minus? What does it do to the pH? It raises it So it makes it more basic, right? So if you have this salt here and you put it into water it's going to break up into these two ions This ion won't react with water but this ion will When it reacts with water, it produces the hydroxide ion which makes the pH go up Does that make sense? So overall, what type of solution will we get here? A basic solution So here, let's formally write this down just to show you really what happens when we react this with water The carboxylic acid Does that make sense? So that, because we have this We're cool with that? Okay, any other questions?
