discuss which of the listed results you would expect for each cell type in each solution. Give explanations for your expectations be specific in your explanations.
A.if you add acid to water should the pH go up down or stay the same?
B. if you add acid to a buffered solution should the pH go up down or stay the same?
C.Why do you think peppers are so important in cells? Be specific. Why does pH need to be controlled in cells

Expert Solution

Ans a-)When an acid is added to the water, the concentration of hydrogen ion increases. Thereby, decreasing the pH of water and hence an increase in acidity. As the carbon dioxide is decomposed to form carbonic acid, which on dissociation will release the concentration of hydrogen ions in water.

Ans b-)When an acid is added to buffer solutiom:
Buffer solution is formed by a strong acid and weak base. Buffer resist a change in pH. if we add the strong acid in buffer solution, the weak base undergoes a reaction and it will react with the hydrogen ions to form a weak acid.
In this case, the hydrogen ions produced will not react with water and thus H3O will not be produced. Instead, they are readily absorbed by A- and thus the pH will slightly change.

Ans c-)Piperine an active compound of Pepper has anti-inflammatory, antigenotoxic, antidepressant and antioxidant properties.
Also, piperine have phenolic and flavonoid content in them which helps to inhibit reactive oxygen species and free radicals.
In order to function optimally, the pH should be maintained and the major role is played by buffer as they resist the change in pH of solution when any acid or base is added to it. Various cellular activities are affected like the growth of cell, substance movement, membrane potential and metabolic processes.
