 So let's do one of these qualitative problems. It says, describe the effect on pH that results from the following addition, potassium acetate to an acetic acid solution. OK, so let's go over what an acetic acid solution is. So this is essentially a little shadowy-ass principal problem is what it is. So acetic acid is CH3COOH, and a solution of it, that means we're dropping it in some water, and that's going to react with the weak acid, acetic acid, to make the conjugate base of acetic acid, the acetate ion, plus H3O+. H3O+, in this reaction equation, is the only thing that affects the pH. So that's where you're getting your pH value from. So it said that we put potassium, what is potassium? Acetate, right? So that's potassium acetate. So when this is put into water, solid, and we put it into water, it breaks up to acetate anion plus potassium, like that. So if we're putting this stuff, potassium acetate, into this solution, what are we really adding to it? We're really adding this stuff to it, acetate anion, this thing here. So if we add this, so let's say we're increase this, that's going to make the reaction go that way. So that means this is going to do what? Concentration of H3O+. Decrease. So that's going to decrease. So that means the pH will decrease. Because the lower your concentration of H3O+, the higher your concentration of OH-, so that's going to increase your pH. Does that make sense? Questions before I kill it?
