Chemical equation balancer
Type the reactants and products, and get the equation balanced with the smallest whole-number coefficients - ionic and redox equations too, with charges balanced - and the count of every atom on each side to check it.
Answer
Cr2O72− + 6I− + 14H+ → 2Cr3+ + 3I2 + 7H2O
Check: atoms on each side
| Element | Left | Right |
|---|---|---|
| H | 14 | 14 |
| Cr | 2 | 2 |
| I | 6 | 6 |
| O | 7 | 7 |
| Charge | +6 | +6 |
Every element, and the total charge, is the same on both sides, with the smallest whole-number coefficients.
