Explanation:
CO2 reacts with water to form carbonic acid as follows;
CO2(g) + H2O(l) ---------> H2CO3(aq)
This makes the solution more acidic hence it will require more NaOH to reach end point due to the increase in acidity.
Hence, if CO2 is not removed by boiling the solution, a greater amount of NaOH is required to reach end point.

Then we would not have oxygen because plants give oxygen in order to breathe
Answer:
Explanation:
Step 1
The question is based on the concept of PH and pOH calculations.
pH is defined as negative logarithmic of hydronium Ion concentration.
while pOH is defined as negative logarithmic of hydroxide ion concentration of the solution.
Step 2
[H+] = 7.7*10-7 M
pH = -log[H+]
= -log ( 7.7*10-7 )
= 6.12
Step 3
pOH = 14 - pH
= 14 - 6.11
= 7.89
