Salts of weak bases and acids

Can someone please explain why salts of weak bases make acidic solutions and salts of weak acids equal to basic solutions? Also is there an easier way to figure out whether a salt is basic, neutral or acidic?

The Conjugate Seesaw????

I understand the concept behind it, stronger acid=weaker base weaker acid=stronger base. However the equation is what I'm confused about. What is Kw supposed to be for?

Re: Section 12.10

Yes, with at least one hydrogen atom bond to oxygen that can dissociate to produce the H+ cation and the anion of the acid and yes theyre the same

Re: orbital vs subshell [ENDORSED]

Orbitals within a shell are divided into subshells that have the same value of the angular quantum number

Re: Acids and bases

Bond strength & Bond polarity:
-the smaller the atom the stronger the bond strength
-When going down a row in the Periodic Table, the atoms get larger so the strength of the bonds get weaker, which means the acids get stronger.

Re: pH of salt solutions

Find the concentration of the salt solution, whether the salt is an acidic, basic, or neutral salt, the equation for the interaction of the ion with the water, the equilibrium expression for this interaction and the Ka or Kb value. Example: Calculate the pH of a 0.500 M solution of KCN. Ka for HCN i...

Re: Lone pairs and hybridization

It has no lone pairs. Along with linear, trigonal bipyramidal, and octahedral they have no lone pairs

Lone Pairs Affecting Bond Angles/Shape?

Part of the topics say: "Explain why lone pairs are more likely to found in certain locations around a central atom and how and why they affect the bond angles in a molecule, cation, or anion." Can someone please explain this specific topic please? Also, what is it called when something ha...

Grading question

Hi! I know that the scale for the class isn't set and that there will be no curving so there is really no way of calculating your own grade. However, I've been re-reading this part of the syllabus: "50% or higher is required to pass with a C- or higher." Does this mean that 250 points will...

Re: G5

For me, I'm having trouble as to how they found the molarity. I thought molarity was (moles of solute (n))/(vol of solute)? After finding the molarity, what is the next step?
