Given that the average pH of clean, unpolluted rain today is 5.4, determine the pH of unpolluted rain 40 years ago. Assume that carbonic acid (H2 CO3) formed by the reaction of CO2 and water is the only factor influencing pH. CO2(9) + H2O(1) H2CO3 (aq) Express your answer using one decimal place. hp ang Private Lodustrial Arca, e city,Chins 12. insert 81 64 4

Could you send your answer and your working too please?

I need full accurate answer with full details. This is my only chance to submit the answers so, solve carefully please.

Number 6

An aqueous solution contains 0.417 M nitrous acid. Calculate the pH of the solution after the addition of 5.38x10-2 moles of sodium hydroxide to 250 mL of this solution.
