An ammonia/ammonium buffer solution contains 0.33 M M NH3 N H 3 and 0.65 M M NH4+ N H 4 + . The Kb K b value of ammonia is 1.8×10−5 1.8 × 10 − 5 . Calculate the pH p H of this buffer.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
