Chemistry Base – a solution that has an excess of OH- ions Bases have a slippery or slimy feel Bases have a bitter taste Bases are corrosive to skin Solutions that are neither an acid or a base is considered neutral
Chemistry pH – stands for potential of hydrogen pH Scale – used to measure if a solution is an acid, a base, or neutral 1-6 acid 7 neutral 8-14 base Neutralization – where an acid is mixed with a base to make the final product neutral
Chemistry 1.What are the characteristics of an acid? A base? 2.What does pH measure? 3.What is neutralization? 4.What contains a lot of H+ ions?
Chemistry Acids and Bases Materials: 1 beaker, 2 test tubes, a test tube rack, litmus strips, vinegar, baking soda solution Measure the pH of the vinegar solution. Measure the pH of the baking soda solution. Mix the two together and then measure the pH of the final solution.
