Storyboard Text

  • Hello, we are currently in a chemistry laboratory.
  • To teach you more about waste disposal !
  • Halogen
  • There are four types waste: halogen, no halogen, acid base and heavy metals waste.
  • First, there are halogen. This is solution with chemical species which are located in the column before the noble gaz.
  • No Halogen
  • Acid Base
  • Heavy metals
  • Halogen
  • Next, there are the no halogen solution which is the rest of the periodic classification except the halogen.
  • Now, we have the acid base solution which are two solutions throw together to adjust the pH.
  • No Halogen
  • Acid Base
  • Heavy metals
  • Halogen
  • The last is the heavy metals solution which is solution with a high density and they tend to be less reactive than lighter metals. They are dangerous for the environment.
  • We don't mix the different chemical products together because the elimination treatment is different for each type and it would be very expensive if we mix them together.
  • No Halogen
  • Acid Base
  • Heavy metals
  • As we said for the heavy metals, which are dangerous for the environment, the pictogram for it is applicable to materials which cause harmful effects on organism in aquatic environment.
  • Also, there is a treatment for the glassware. For this, if we break a glassware, we have to put it here.
  • Glassware
  • To conclude, in a chemistry laboratory it's essential to do a waste disposal to not affect the environment and also it's an economic question.
  • Halogen
  • We hope that you understand why it's important, goodbye !
  • No Halogen
  • Acid Base
  • Heavy metals
