hi all, i am new here. just need some practical help with something that is stumping me. I have a stock solution of Malachite Green Oxalate . i would like to be able to determine, or confirm the concentration of the solution. do any of you know an easy way for me to do this. ? btw , i am not a student etc. this needs to be a simple test i can do at home. cheers all Russell.
