All please 3. Arsenic trioxide, As:0s, is an odorless white powder that has relatively high solubility in water. It is alsoan extremely toxic poison, and causes symptoms similar to cholera. Until the invention of the Marsh test inmid-1830s, detecting the presence of arsenic trioxide in the body was nearly impossible. In the Marsh test, asample suspected of containing arsenic trioxide is treated with zinc metal and a strong acid. The zincspontaneously reduces the arsenic in As,0, to As", which in the acidic solution becomes protonated to formarsine (AsH1) gas. The detection of arsine gas indicates a positive test for arsenic trioxide. The Marsh test iscapable of detecting as little as 10 ug of arsenic trioxide.Zn(s) + As,0, (aq) → AsH, (g) + Zn" (ag)a. How many zinc atoms must be oxidized to detect 10 ug of As,0,?b. How many total electrons are transferred in part (a)?c. How many times does the reaction occur in part (a)?
