1. The problem statement, all variables and given/known data okay so im going to do a lab on reaction rates, theres a table given (effects of varying concentration) there are 9 reactions, I will just give one, ( if i can figure this out ill figure out the rest on my own) so reaction #1 flask A contains 7.50mL of .200M KI none of .20 M KCI .0050 M S2O3^-2 1 drop of starch flask B contains 7.5 mL of .100M S2O8^-2 It says for each reaction determine the concentration of KI, (NH4)2S2O8, and Na2S2O3 that will be present when solution A and B are mixed together. the total volume for each reaction is 20.0 mL. 2. Relevant equations M1V1=M2V2 ? 3. The attempt at a solution I'm not sure how to begin this, would I have to use the M1V1=M2V2 ? how would I set it up ?
