This preview shows page 1 - 3 out of 5 pages.

2. To your drop of base that wicked into the paper towel, add 1 drop of BTB. Record the color in Table 1.2. Third , you will see what happens when your previous acid plus BTB drop and base plus BTB drop have acid or base added to them respectively. 1. To your drop of acid plus a drop of BTB (currently a colored spot on the paper towel), add 1 drop of base. Record the resultant color in Table 1.3. 2. To your drop of base plus a drop of BTB (currently a colored spot on the paper towel), add 1 drop of acid. Record the resultant color in Table 1.3.
Fourth , you will see what happens when the drops merge on the paper towel. 1. Fold a new piece of white paper towel so that it is four layers thick and flatten it. 2. You will drop a drop of acid and a drop of base side by side on the paper towel such that they will wick close to each other. Use your previous diameter measurements to determine how close you should place these drops. 3. Next, drop a drop of BTB directly in between the drop of acid and the drop of base, and begin observing color changes. Record these initial color changes and the stagnant colors. You have space for only five observations in Table 1.4, so pick your favorite five. Table 1.1 Reagent Diameter that 1 drop of liquid wicked Acid (HCL) 21 mm Base (KOH) 23 mm Diameter of BTB’s color wicked Color of BTB as it remained on paper Bromothymol Blue (BTB), 0.04% 20 mm 10 mm Yellowish blue Table 1.2 Observation Your inference about what happened Color of BTB drop on previous acid drop is:
