Question
Transcribed Image Text:A 1L distilled water sample is allowed to equilibrate with the atmosphere.
a) The global average CO2 content in the atmosphere is 0.0355% as of 1991 and is increasing at a rate of
~ 1% per year. What is the pH of the sample? NOTE: Consider 2021.
b) 5 ml of 1M NaOH was added to the sample and allowed to equilibrate with the atmosphere. Find the
pH neglecting the dilution effects. Hint: use charge balance equation.
c) Find the pH immediately after the addition was done in 1b.
d) Explain the reason for the observed difference in pH in 1b and 1c.
