Spot the mistake...

Level pending

During a vacation, the Tan family was at an overseas chemistry laboratory. Mrs Tan wanted to get samples of solutions as souvenirs based on her children's favourite colours:

  • Benedict - green - iron (III) nitrate

  • Bob - blue - copper (II) sulfate

  • Brenda - red - iron (III) thiocyanate

  • Brian - orange - potassium dichromate

  • Billy - yellow - potassium chromate

However, Mr Tan pointed out that ONE of his children will NOT be happy with what they receive.

Benedict, Bob, Brenda, Brian or Billy?
