The dipole moment in a water molecule Which statement about hydrogen bonds is NOT true? A) Hydrogen bonds account for the anomalously high boiling point of water. B) In liquid water, the average water molecule forms hydrogen bonds with three to four other water molecules. C) Individual hydrogen bonds are much weaker than covalent bonds. D) Individual hydrogen bonds in liquid water exist for many seconds and sometimes for minutes. E) The strength of a hydrogen bond depends on the linearit...

Acid : proton donor base : proton acceptor conjugate base : what is left after an acid gives up a proton Strong acids : HCl, HBr, H2SO4, HI, HNO3, HClO4 strong base : group 1 hydroxide (NaOH, KOH, Ca(OH)2) strong acids have 2 | P a g e : weaker conjugate base weaker acids have : stronger conjugate bases weaker bases : resonance, more electronegative groups buffer : equal amounts of acid and base, pH=pKa equivalence of strong acid and strong base : equal mols of acid and base...

1. A weak acid, HA, has a pKa of 4.11. a) At pH 7.11, what will the ratio of conjugate base to acid be? (Henderson-Hasselbach equation: pH=pKa + log [A-]/[HA]) b) Based on answer to "a," is there more HA or A- at that pH? c) At pH 2.11, what will the ratio of conjugate base to acid be? d) Based on answer to "c," is there more HA or A- at that pH? e) At pH 4.11, what will the ratio of conjugate base to acid be? f) Fill in the blank: if pH is greater than the pKa of a weak acid, there w...

Acid-Base Equilibria Bronsted-Lowry theory of an acid? - correct answer An acid is a substance which can donate a proton (H+) to a base. Bronsted-Lowry theory of a base? - correct answer A base is a substance which can accept a proton (H+) from an acid. (N.B. All bases must have at least one pair of electrons to be able to accept a proton. T/F: When an acid loses a proton to a base, it forms a base itself. - correct answer True. Similarly, when a base accepts a proton from an acid, it for...
