OChem and ADA sample exam question

[CALgoob]

i was wondering if there was a difference between K2Cr2O7 and Na2Cr2O7 and also between NaOC2H5 and KOC2H5...

also, im pretty positive the ADA sample exam is much easier than the real DAT but can someone give a more specific breakdown?

thanks for your help!

All forms of Cr +6 are powerful oxidizing agent, that's all you need to know.. Figure out the oxidation state to confirm and you be golden..
