Question

Describe the apparent relationship between H30 and OH concentrations when an endpoint is reached in acid-base titration.

Answer 1

H3O aproximately equal to OH concentration.

Answer 2

I suppose the answer here is that the (H3O^+) = (OH^-) and I think that answer is good BECAUSE you said "apparent" end point but ONLY because of that. For equivalence points that occur at pH = 7.0, the H^+ and OH^- are equal but at equivalence points not at 7.0 that is not true. The H^+ is larger than OH^- at methyl orange and methyl red end points and OH^- is larger than H^+ at phenolphthalein end points.

Answer 3

This is not useful at all

Answer 4

This Was Very Useful.

Answer 5

How could someone not find this useful, if you're taking chemistry it shouldn't be difficult to understand his explanation?
