Question 1

Consider the titration of 100.0 mL of 0.10 M H2A (Ka1 = 1.5 × 10–4; Ka2 = 8.0 × 10–7) with 0.20 M NaOH. Calculate the volume of 0.20 M NaOH required to reach an [H+] of 6.0 × 10–4M.

◦ 0 mL
◦ 10. mL
◦ 25. mL
◦ 50. mL
◦ 65. mL

Question 2

Consider the titration of 100.0 mL of 0.10 M H2A (Ka1 = 1.50 × 10–4; Ka2 = 7.82 × 10–7) with 0.20 M NaOH. Calculate the [H+] after 75.0 mL of 0.20 M NaOH has been added.

◦ 1.6 × 10–6M
◦ 1.3 × 10–8M
◦ 3.9 × 10–7M
◦ 7.8 × 10–7M
◦ None of these are correct.

Astigmatism is the most common vision problem. It may accompany nearsightedness or farsightedness. It is usually caused by an irregularly shaped cornea, but sometimes it is the result of an irregularly shaped lens. Either type can be corrected by eyeglasses, contact lenses, or refractive surgery.

Cocaine was isolated in 1860 and first used as a local anesthetic in 1884. Its first clinical use was by Sigmund Freud to wean a patient from morphine addiction. The fictional character Sherlock Holmes was supposed to be addicted to cocaine by injection.

Autoimmune diseases occur when the immune system destroys its own healthy tissues. When this occurs, white blood cells cannot distinguish between pathogens and normal cells.

Did you know?

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
