a. What is the concentration of [H+]?
In order to use the stomach acid in another experiment, a biologist must dilute 10 mL of the acid solution to a pH of 5.
b. Assuming all H+ comes from HCI, how many grams of sodium hydroxide are necessary to obtain a pH of 5? Include a balanced chemical reaction for this process.
c. Is the neutralization reaction above exothermic or endothermic?
*Jenna Bartz took Chem 13H in 2000. I suppose if you have this many creative problems, you are likely to be the grader in a later year, as Jenna was for the class in 2001. She helped design the homeworks for 2002, but did not select this problem.
