Answer:
Answer (a) C
(b) B
Explanation:
Attached to this answer is a picture to explain better the answer provided
(a) If solution and pure solvent are both separated by semi- permeable membrane, osmosis is said to occur from higher concentration to lower concentration of solvent . The solution with the least concentration will absorb least amount of H2O
In the attached file tube C will absorb the least amount of H20, therefore the least concentrated solution is C
(b)The largest number of dissolved ions is said to be in the solution that absorb maximun amount of H2O because osmotic pressure is said to be high in it.
Tube B has the highest number of dissolved ions

Answer:
pH is 8.52
Explanation:
According to the working in the photo
<span>In terms of energy and entropy, systems in nature tend to undergo changes toward lower energy and higher entropy. Entropy is important as it describes the flow and distribution of energy. For a process to to occur spontaneously, it is a necessary condition that the entropy of the system undergoing the process to increase. If the entropy decreases, then that process cannot occur spontaneously. It needs some work/ energy to be pumped in in order for the process to occur</span>
