What do I know? (What do I remember about the neutralization reaction) Neutralization is when an acid and base are mixed together to me an ionic compound or which are 7 on the pH scale or pure water, it is also when a base and acid are mixed to make it in a neutral state. What am I wondering? (What are your rough ideas to fix an acidified lake?) I will be finding a base that will work the most effective way, also I will find a base that can fix a large amount of acidified lake water with a base that can neutralize it with less then the acidified lake water, I will also look for a base that can make sulfuric acid neutral As a class we got options to what we will conduct this experiment with the base I choose is Sodium hydroxide (NaOH) and for the indicator to show that this will make it neutral is the Universal Indictor I choose that indicator because it has a wide color spectrum when being neutralized. Predictions
How much base do you think do you think it will take to neutralize 5mL of acidified lake water? Why? I believe that it will take a little less then 5mL to neutralize it because it will rapidly dissolve and neutralize it. I also know because sodium hydroxide is very responsive once added it will take effect. Balanced Chemical Formula for Sodium hydroxide and Sulfuric Acid (Acidic Lake water) NaOH + H2SO4 ----------------> NaHSO4 + H2O
How will you know when you have added the correct amount of base and why? I will be using the universal indicator when first added it will first be red, orange, and yellow thus meaning it’s an acid. I will know when it’s fully neutralized when it turns green, blue, and violet. I choose this indicator because it has a wide spectrum of colors, which can help me indicate if I have added the right amount of base.
Experimental Set-up and procedure
1. First get all safety equipment needed (safety goggles, and glasses) 2. Receive a test tube
