Re: Henderson-Hasselbalch Equation

Since weak acids and weak bases barely dissociate, we use the Henderson-Hasselbalch equation to approximate the pH of buffer solutions using initial concentrations as addition of a small amount of acid or base does not alter the pH of a buffer solution. For strong acids and bases we can directly use...

Re: Light emission ranges

It is easier to remember that the visible range is 400-800 nm and anything below is ultraviolet and anything above is infrared.

Re: ICE Chart Original Value Change

We push back the products in cases where the icebox does not help solve the quadratic equation and all the terms cancel out.

Re: Bonds

No, it counts a single region of electron density, and this is helpful when you are doing hybridisation.

empty D orbitals

What elements should we consider while drawing lewis structures having empty d orbitals to substitute single bonds with double bonds so the structure becomes more stable?
