Confused about how to calculate Concentration for this lab
« on: November 05, 2010, 04:44:07 PM »
Ok well my lab states to add .1g of salicylic acid to a 250mL volumetric flask. Then add 5mL of 1M NaOH, then dilute to the mark with water.

Im confused on how to calculate the concentration for this since the first stage would be .1g of salicylic acid being mixed with the NaOH. Would that create a concentration? or react?

I tried using the MV=MV equation but i dont think thats the right way to do it..

using MV=MV is wrong because you don't have a dilution you have a reaction. The reaction is between the acid and NaOH which is a base, you need to establish a stoichiometry relation and see which one is the limiting reagent. the you can easy determine the concentration
