Problem 58E

What volume of 0.200 M ethanol solution contains each amount in moles of ethanol?

a. 0.45 mol ethanol

b. 1.22 mol ethanol

c. 1.2 × 10-2 mol ethanol

Step-by-Step Solution:
Step 1 of 3

Solution 58E: Step1: We can say that all metals are not equally reactive. That is why, reactive metals can displace less reactive metals from their compounds in solution or molten form. In order to know, which metal is more reactive, several experiments were performed, and finally a series known as the reactivity or activity series was developed.The metals at the top of the activity series are readily oxidized and are less stable whereas those at the bottom of the activity series are least readily oxidized and are more stable. Step2: Let us consider the two reactions given above. Br2aq) + 2NaI(aq) ------> 2NaBr(aq) + I (aq) 2 ------(1) Cl2aq) + 2NaBr(aq) ------> 2NaCl(aq) + Br (aq) 2 ------(2) a) In equation (1), we have seen that, bromine replaces iodine from its salt solution. This indicates that bromine is more reactive than iodine and hence is less stable. Again, in equation (2), it is seen that, chlorine replaces bromine from its salt solution. Hence, chlorine is more reactive and less stable than bromine. The increasing order of stability of the halogens is as follows: Cl < Br < I Thus, iodine is the most stable elemental halogen. b) As we have seen in the above equations (1) and (2) that chlorine is more reactive and less stable compared to iodine. So, when mixed with potassium iodide, chlorine will replace iodine from its salt solution. The chemical reaction involved is given below: Cl2aq) + 2KI(aq) ------> 2KCl(aq) + I (aq)2 c) As we have seen in the above equations (1) and (2) that bromine is less reactive and more stable compared to chlorine. So, when elemental bromine and lithium chloride are mixed, no reaction occurs. Br (aq) + LiCl(aq) ------> No Reaction 2
