Ag2Cro4

  1. silver dichromate

  2. silver chromium

  3. silver chromate

  4. silver subchromate
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Ag2CrO4 is silver chromate, formed from silver ions (Ag+) and chromate ions (CrO4 2-). The charges balance: two Ag+ ions (total +2) with one CrO4 2- ion (-2). Silver dichromate would be Ag2Cr2O7. Chromate and dichromate are different ions.
