Procedure: I have a well-plate-96‚ a piece of white and black paper‚ and the chemicals from the Observation of Chemical Changes Experiment Bag. I used a different well for each combination of solutions. I placed two drops of one chemical then two drops of a different chemical. Observation: NaHCO3 and HCl - Clear bubbles; bubbles did not fizz. HCl and BTB- Color changes to orange
