3. Standard white vinegar you can buy in the grocery store is 5% concentration. That means 5% of the liquid vinegar is acetic acid and 95% of the solution is water. In a hardware store, you can buy industrial strength vinegar, which is 30% concentration. This means that 30% of the vinegar is acetic acid, and the remaining 70% is water. Samuel does another experiment, this time with 5% vinegar and 30% vinegar. He sets up two science fair volcanoes (in no particular order), each with the same temperature, mass of baking soda and volume of vinegar. But one volcano uses 5% vinegar and the other volcano uses 30% vinegar. He measures the volume of gas production for the first minute of each reaction, and he records the data below. Volcano # 1 Volume of gas Volume of gas produced (mL) vs. Time (s) for Volcano #1 Time (s) produced (mL) 60 E 50 10 25 40 20 38 30 46 30 • Volume of gas produced (mL) 40 50 50 52 10 60 53 20 40 60 80 Time (s) Volcano # 2 Volume of gas produced (mL) vs. Time (s) for…
