1) Was the pH of any of the solutions significantly different than what you hypothesized? Explain 2) What is the pH range of the solutions you tested? Are any of the solutions very acidic or very basic? 3) What does pH measure? 4) Compare the hydrogen ion concentration in vinegar to window cleaner. 5) Is pH an absolute or a relative measure? Explain 6) Word Origins. The p in pH stands for the German word Potenz, which means "power" or "potential". The H represents the hydrogen ions (H+). How are these related to the definition of pH? 7) Describe the relationship between the hydrogen ions (H+) and pH. How is pH related to a solution’s acidity? 8) Do you notice anything about the solutions on the pH scale, their pH, and their location on the pH scale?

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
