Solutions can be made to have delayed reactions. Delayed reactions are interesting to watch but can they might be able to speed up the process of their reactions. Delayed reactions can be speeded up to have a quicker reaction than the normal reaction/control group. The control group takes about 15 seconds for the chemicals to react. The 1st chemical is clear/optical and has no smell which will be referred to as Solution A/S.A. The 2nd chemical has to layers but when shaken it turn cloudy and smells, and which will be referred to as Solution B/S.B. Both chemicals are at room temperature. 10mL of Solution A is be poured into a granulated cylinder and set aside. 10 mL of Solution B is poured into a granulated cylinder and set aside as well. …show more content…

Independent variables are not dependent to anything, Independent variables can be changed, and manipulated to work however the experimenter wants it to work. So to speed up the reaction with Solution A, Solution B will be decreased. The less Solution B there is the less time it takes for Solution A to react with S.B. If there is less S.B there will be an instant/almost instant reaction for the two chemicals to create the rich blue substance. Solution B will be decreased by 2mL in 5 trials. Solution A will stay the same since only Solution B Is being changed and there can be only on the variable change to make the result/conclusion valid/accurate. Have 350ml beaker clean, dry and no trace of any other chemical it might have contained before this experiment and set aside on the …show more content…

Be ready to start the timer when the 6 mL S.B is poured in the 350mL beaker containing S.A. Stop the timer when the color blue start to appear in the solution inside the 350 mL beaker. Rinse and dry the 350 mL beaker that contained the solution. Set the dry 350 mL beaker aside Pour 10 mL of S.A in one of the two granulated cylinders. Make sure S.B is completely mixed so no layers are shown before pouring 4 mL of S.B in the other granulated cylinder that does not contain S.A. Pour all of the 10 mL of S.A into the dry 350mL beaker that was set aside. Be ready to start the timer when the 4 mL S.B is poured in the 350mL beaker containing S.A. Stop the timer when the color blue start to appear in the solution inside the 350 mL beaker. Rinse and dry the 350 mL beaker that contained the solution. Set the dry 350 mL beaker aside Pour 10 mL of S.A in one of the two granulated cylinders. Make sure S.B is completely mixed so no layers are shown before pouring 2 mL of S.B in the other granulated cylinder that does not contain S.A. Pour all of the 10 mL of S.A into the dry 350mL beaker that was set
