Are you doing a research on C5 burning?I am Zy from China.
The choices can be found elsewhere and as follows:
<span>A. 0.3
B. 3.9
C. 8.4
D. 11.7
</span>
I believe the correct answer is option B. <span>The pH of apple juice ranges from 3.35 to 4, which indicates it is on the acidic side of the pH scale. Hope this answers the question. Have a nice day.</span>
Osmotic pressure is defined as the pressure that must be applied to the solution side to stop fluid movement when a semipermeable membrane separates a solution from pure water.
<h3>Why is it called osmotic pressure?</h3>
The net flow of solvent through a semipermeable membrane is called osmosis (from the Greek osmós, meaning “push”). The direction of net solvent flow is always from the side with the lower concentration of solute to the side with the higher concentration.
<h3 /><h3>What is the role of osmotic pressure?</h3>
Osmotic pressure is of vital importance in biology as the cell's membrane is selective toward many of the solutes found in living organisms. When a cell is placed in a hypertonic solution, water actually flows out of the cell into the surrounding solution thereby causing the cells to shrink and lose its turgidity.

Answer:
Acid base titration curves shows the pH at equivalence point
Explanation:
Since the images were not shown, I will proceed to give a general description of the following acid-base titration curves:
In a strong acid-strong base titration, the acid and base will react to form a neutral solution. At the equivalence point of the reaction, hydronium (H+) and hydroxide (OH-) ions will react to form water, leading to a pH of 7.
The titration curve reflects the strengths of the corresponding acid and base. If one reagent is a weak acid or base and the other is a strong acid or base, the titration curve is irregular, and the pH shifts less with small additions of titrant near the equivalence point.
Polyprotic acids are able to donate more than one proton per acid molecule, in contrast to monoprotic acids that only donate one proton per molecule. In the titration curve of a polyptotic acid and a strong base, The curve starts at a higher pH than a titration curve of a strong base. There is always a steep climb in pH before the first midpoint. Gradually, the pH increases until it passes the midpoint; Right before the equivalence point there is a very sharp increase in pH.
