Homework Statement
Help! I am confused with my assignment. it was about complex acid base titration. the analyte was citric acid and the titrant was a base. To find it, I need to search for C1V1=C2V2, however during the balanced equation, there is 3 mol of my base that will be reacting to 1 acid. Will the ratio of mol be included in the C1V1=C2V2 equation.? Lets say that C1 is the acid and C2 is the base. What will the equation now? the volume of C2 is missing
Relevant Equations
C1V1=C2V2

Forget about C1V1=C2V2, just go for stoichiometry and moles.

Compare with http://www.titrations.info/titration-calculation

The idea of using C1V1=C2V2 to facilitate calculations does IMHO more harm than good to students - they never remember the logic behind, they think the shortcut is the right thing.
