Answer:

a) Photosynthesis ( 6CO₂+ 6H₂0 ------> C₆H₁₂0₆ + 60₂): pH increases

b) Respiration ( C₆H₁₂0₆+ 0₂ ----> CO<u>₂</u>  + H<u>₂</u>O + ATP): pH decreases

c) Contamination with substance that releases hydroxyl/hydroxide ions: pH increases

d) Contamination with substance that releases hydrogen ions: pH decreases

Explanation:

(1) More the acidic environment, lesser will be the pH.

(2) More will be the basic environment, more will be the pH.

<u>a) Photosynthesis ( 6CO₂+ 6H₂0 ------> C₆H₁₂0₆ + 60₂): pH increases:</u>

During photosynthesis, carbon dioxide (CO₂) is utilized to produce oxygen (O₂). CO₂ is responsible for making the environment acidic because it has tendency to combine with water (H₂O) so as form form carbonic acid (H₂CO₃). The reaction is mentioned as under:  

                  CO₂ + H₂O  ⇄  H₂CO₃

But, during photosynthesis carbon is being used as a result of which it's concentration is decreasing in the environment. Less CO₂ means less acidic environment leading to an increase in pH.

b) Respiration ( <u>C₆H₁₂0₆</u>+ <u>0₂</u> ----> CO<u>₂</u>  + H<u>₂</u>O + ATP): pH decreases:

During respiration, carbon dioxide (CO₂) is being produced as a result of which environment will become more acidic leading to a decrease in pH.

c) Contamination with substance that releases hydroxyl/hydroxide ions: pH increases:

When hydroxyl/hydroxide ions [OH⁻] in the environment increase, it adds to the basicity and decreases acidity. An increase in basic environment leads to an increase in pH.

d) Contamination with substance that releases hydrogen ions: pH decreases:

When hydrogen ions [H⁺] in the environment increase, it adds to the acidity and decreases basicity. An increase in acidic environment leads to a decrease in pH.
