I need help with the acids and bases unit.
how would I get the hydronium ion concentration from volume and
pH.
how do I get pOH from hydronium ions
how do I get pH when I have Concentration
if chemicals have the same molarity how would I know
which is a stronger acid (they aren't in data book)
how would I know which is more conducive to least
how would I know which has a higher OH- concentration

Pure water will auto-ionize to produce a hydronium ion and a hydroxide ion: 2H2O --> H3O+ + OH- comapare the componets within the final reaction mixture. It would contain A) More water molecules because water is turner acid and base than H3O+ and OH- B) More water molecules because water is a weaker acid and use than H3O+ and OH- C) More H3O+ and OH- because the ions are stronger acid and bases than water molecules D) More H3O+ and...

I am studying Acids & Bases. I understand that Acids ionize, creating ions that were not previously there. I understand that Bases dissociate, simply breaking the compound apart into its individual ions. Acids ionize to create (H3O) ions by producing/donating an (H+) ion Bases dissociate, with one ion being (OH-) But I am confused about the Bases.... I get that the compound breaks apart, and that bases dissolve/accept protons but if you are looking at this chemical equation, which dissociates...

Lab 5 Buffers 1. Dissolved ions in salt solutions can act as acids or bases and react with water to produce hydronium ions or hydroxide ions that contribute to the pH of the salt solution. Since strong acids and strong bases completely ionize in solution, the reverse reaction essentially does not occur, meaning that the resulting conjugate base of a strong acid or conjugate acid of a strong base do NOT act as acids or bases. Ions that are conjugate...
