FeBr3 : What is the formula of cation or anion for this ionic formula?
1 answer:
The ionic compound Fe Br3 is electrically neutral.
The oxydation state of Br is -1, which gives a total of 3 negative charges, when you multiply 3 ions times -1 charge.
Then the oxydation state of Fe has to be 3+.
Then the compound is formed by two charged particles, Fe+3 which is positively charged ion or cation, and Br - which is negatively charged or anion.
The algebraic sum of the charges of the ions must result 0 (neutral state).

Explanation:
- The products formed are chromic chloride and cobalt.
Chromium + Cobaltous Chloride = Chromic Chloride + Cobalt
- Type of reaction is Single Displacement (Substitution) which is there is a displacement of one atom.
Reactants used in the reaction are -
- Chromium
- Cobaltous Chloride
Products formed in the reaction are -
- Chromic Chloride
- Cobalt
Hence, the chemical reaction is as follows -
→
For balancing the above chemical equation we need to add a coefficient of 2 in front of chromium and of 3 in front of cobalt(II)chloride on right-hand-side while of 2 in front of chromium chloride and of 3 in front of carbon monoxide on left-hand-side of the equation.
Hence, the balanced equation is -
