How would the results turn out if a student forgot to read the label on the jar carefully and put potassium chloride in the crucible instead of potassium chlorate?

Answer 1

If a student accidentally put potassium chloride instead of potassium chlorate in the crucible during a lab experiment, the results would likely not match the expected outcome. Potassium chloride does not release oxygen when heated like potassium chlorate does, so there would be no oxygen to react with the magnesium present in the crucible. This would impact the ability to achieve the desired chemical reaction and may lead to incorrect data or observations.
