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 inegar, 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 produced (ml.) vs. Time (s) for Volcano #1 Time Volume of gas (s) produced (ml) 60 50 25 10 20 40 38 30 46 Volume of gas produced (ml) 40 50 50 52 53 60 20 40 Time (s) 60 Volcano # 2 Volume of gas produced (ml) vs. Time (s) for Volcano 2 Volume of gas produced (mL) Time 10 10 20 30 19 30 25 26 33 39 45 Volume of gas produced m) 40 50 S 10 60 60 (u) peonpod seb jo ounon (u) peonpoad sed jo ounoA
