    Introduction to Acids Base chemistry Purpose How to determine the constant equilibrium of an acid‚ Ka? How to evaluate the concentration (M) of an acid? In “part A” experiment‚ we would test the PH of different concentration of acetic acid (a weak acid which partially dissociated in water) with a PH probe. After we got the PH‚ we could find out the concentration of H+ by applying the relationship pH = -log [H+]. Having the determined value of [H+] of a weak acid with a known molar concentration

    How Acetylsalicylic Acid was Discovered Acetylsalicylic Acid in its earliest form was a powder for the bark and leaves of the willow tree. Hippocrates‚ who lived sometime between 460 B.C. and 377 B.C‚ founded it. This “Miracle Drug” that was able to relieve pains was later looked into with further detail by Johann Buchner. He isolated a tiny amount of bitter tasting yellow‚ need- like crystals‚ and called salicin. By 1829 French Chemist Henri Leroux had improved the extraction procedure to

    Contrary to many people’s thoughts about seasons‚ summer is not due to the Earth being closer to the sun and vice versa for winter (these differences are extremely small). The Earth moves around the sun anti-clockwise in an elliptical orbit‚ with one revolution representing a year (365.256 days). To complete the orbit‚ Earth travels at an approximate speed of 67‚000 miles an hour. While we are orbiting around the Sun‚ we are also rotating around an imaginary axis of the earth‚ with one revolution

If I only dissociate to the extent of 1.50%‚ what is the value of my Ka? 3. I am a 0.20 M solution of hydrocyanic acid‚ HCN‚ with a Ka of 4.93 x 10¯ 10 . What is my pH? 4. I am a buffer made from 0.10 M acetic acid and 0.15 M sodium acetate. If the Ka for acetic acid is 1.77 x 10¯ 5 ‚ what is my pH? 5. I am
