The poH of a solution containing 1 M HCI is: A) 0.0 B) C) 4.0 D) 7.0 E) 3.0 12. The aqueous solution with the lowest pH is A) 0.01 M HC B) 0.1 M acetic acid (pKa 4.86). C) 0.1 M formic acid (pKa 3.75). 10-1 M D) HC E) 10 M NaOH 13 The poH of a solution is 8.6, while gastric juice is pH 14. The gastric juice has A) 0.189 times the [H as the solution B) 7.2 times higher [H j than the solution C) 10 thousand times higher [H than the solution. D) 7,000 times lower [H than the solution. E) 10 million times higher [H than the solution 14. Based on the Henderson-Hasselbalch equation, calculate poH when acetic acid is 50% dissociated to acetate (the pKa of acetic acid is 4.76; pH pKa log [Ayog HAD Indicate whether the solution is acidic, basic, or neutral. A) 5.36; acidic B) 7.00; neutral C) 4.76; acidic D) 9.24: acidic 9.24; basic E)Explanation / Answer
10. Cell A and b has same composition. both have 10,000 glucose units. When they are placed in hypotonic solution, they will shrink to the same extent.
On keeping the cells in hypotonic solution, water from the cell start moving outward because of low conc outside the cell and water moves from high conc. to low conc. resulting in the shrinkage of cell.
11. Answer is c. 14
pH=-log[H+]
pH=-log(1)= 0
pH+ pOH=14
pOH= 14-pH= 14-0= 14
