You are on a mission to evaluate zinc deficiency in a 3rd world country. You draw whole blood samples into red top tubes on 20 children in a small village early in the morning before they have eaten breakfast and transport the tubes 100 miles back to the city hospital, where flame atomic absorption spectrometry is performed the following day. None of the children has a low zinc level; in fact, many have significantly elevated levels. Explain the results.

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
