Acid and Base Project
By: Jack Rathe, Emerson Clark, Jai Sharma
Acids vs. Bases
7: Neutral (water)
Acids: They are substances that break off an aqueous solution to produce hydrogen ions.
Bases: They are substances that produce hydroxide ions in a solution.
Neutral Solution: This solution is neutral if the hydrogen ion concentration is equal to its hydroxyl ion concentration.
Procedure-Explanation/Documentation of Experimental Methods
Problem: We need to find out the pH level of 12 different liquids.
Hypothesis: If we test each liquid with a pH strip, then we will find of the pH level of each liquid that we are testing.
Read through all project guidelines
Find out which ones are bases and acids
Obtain each type of liquid
Obtain Ph strips
Test each strip in each type of liquid
When putting each strip in the liquid
Take picture of Ph strip
Record on data table all Ph levels
Repeat steps 3-8 for each substance
Materials: pH strips, 12 different liquids, tongs to hold them, camera to take picture, pen, piece of paper for the background
Variables: IV: Different types of liquids DV: The pH level of each liquid Controlled Variables: The length and size of each pH level
