Question

what will happen if K2 cr2 O7 mixed with HCl​

Answer 1

Answer:

With K2Cr2O7 and HCl: The H+ ions from the acid combine with the oxygens from the oxidizing agent to make water molecules. When said agent gets reduced, K+ and Cr3+ ions are left over. These combine with the Cl- ions from theHCl to leave KCl and CrCl3 in solution.
