Question
Consider the solutions that exist on either side of the semipermeable membrane in the illustration below to answer questions 83 - 85. In which direction, left to right, right to left, or neither will osmosis force water molecules to travel through the semipermeable membrane? Assume the calcium chloride concentration is doubled. In which direction, left to right, right to left, or neither will osmosis force cations to travel through the semipermeable membrane? Assume the calcium chloride concentration is reduced by one half. In which direction, left to right, right to left, or neither will osmosis force chlorine ions to travel through the semipermeable membrane? In the reaction Fe + CuSO_4 rightarrow FeSO_4 + Cu: Which element (or ion) is oxidzed? Which element (or ion) is reduced? Which element (or ion) acts as the oxidizing agent? Which element (or ion) acts as the reducing agent? In the reaction 2C_4 H_8 + 12O_2 rightarrow 8CO_2 + H_2 O Which element (or ion) is reduced? Which element (or ion) is oxidized?Explanation / Answer
83) Conc. of water on the left is more than that on the right. Hence water molecules will flow from L to R
84) Conc. of cations will be more on the right than that on the left. Hence cations will flow from R to L
85) Conc. of Chloride ions will be more on the left than on the right. Hence the flow will be from L to R
86) Fe is oxidized to Fe2+
87) Cu2+ is reduced to Cu
88) Cu2+ acts as oxidizing agent
89) Fe acts as reducing agent
90) O is reduced
91) C is oxidized
