Question

whats a "non-quantitative" reaction?

anonymous · Answer

like between weak acids and bases|dw:1433736747661:dw|   it will look kinda like that but im not sure if there is or not....  


im thinking no......

i still dont know what you mean. what are the axes on the graph?

anonymous · Answer

y is pH x is the titrant which is a base, so if you add a weak acid and weak base together its a non-quantitative rxn therefore that graph and it literally looks like thaat while for strong acids and strong base it will look like this |dw:1433810589881:dw|  

but becuase WA and WB   have the graph like that is there still a equivalence point?

aaronq · Answer

oh okay. yes, they do have equivalence point, although they're not as pronounced as those with strong acids/bases. this type of equivalence point would probably only be apparent after some data processing - which would involve taking som derivatives to find any inflection points
