WebApr 30, 2024 · It is of paramount importance to note that, in chromate, the chromium atom does not have the charge of a bare cationic species (Cr n+ ), but has that of an oxyanion (CrO 42−) one. Thus, the charge of a chromate anion is 2− and the oxidation number of chromium is +6, i.e., Cr (VI) or Cr +6. This is presented illustratively in Table 2. WebThe net ionic charge is nothing but the number of cations or anions a chemical compound is having. The ionic formula can be written in 2 ways, one is general method and the other is a criss-cross method. Example: Question: Calculate the net ionic charge of Na+ Answer: Given Na + The ion name is sodium cation or sodium ion Net ionic charge is +1

WebJun 8, 2013 · The four waters do not have net charge. The remaining ligands--the three Cl's--are likely C l X −, and so their total charge contribution is − 3. The only way the complex can be neutral is if the chromium has a + 3 charge: hence Chromium (III).
