Neutralization

 Aim: To observe a neutralization reaction

Method 1: Add approximately 1-2 ml of Na Co and place the test tube into the test tube rack. Add 3-5 drops of universal indicator solution. Method 2: Using a dropper bottle, add HCI drop by drop. Be careful because adding even a small amount of extra acid can mean you'll miss the neutralization point.

Equipment: Test tube rack, universal indicator, Base, Acid

Results: It changed colors like red, yellow, orange, blue, purple etc

Discussion: What does the results mean? When doing the neutralization experiment there was a chart that we had to use, we had to base the results off of the chart according to the colors, from red to orange, yellow, green, blue, indigo and lastly violet. If the color was in between the range from red, orange to yellow that would mean that it would be an acid the more stronger the color was the more stronger the chemical was, so, if the color was red that means it would be a strong acid but if it were to be orange or yellow that mean its a weak acid, if it was violet that would mean its a strong base but if it were to turn indigo or violet then that indicate that it was a weak base.
